    491: Reinis Krēgers on Play-Based Athleticism and Elastic Power Development
    Nov 27 2025
    Today’s guest is Reinis Krēgers, a former champion decathlete turned track and physical education coach. Reinis is dedicated to building complete movers: fast, coordinated, confident athletes who understand their bodies. His training blends classical sprint development with exploratory tasks, helping athletes develop physical literacy and long-term adaptability. In sports performance, we often fixate on exercises, cues, and optimizing micro-qualities in the moment. What we discuss far less, yet what often separates the elite, is the role of play, creativity, and culture. By looking closely at events like the pole vault and hurdles, we can see how a developmental, curiosity-driven approach benefits athletes of every sport. In this episode, Reinis shares the remarkable story of losing a finger, training exclusively with his non-dominant hand, and still setting a shot put PR. This opens the door to a rich discussion on cross-education, novelty, and how the brain actually learns movement. We explore play-based coaching, pole vault as a developmental super-tool, contrasts between Eastern and American coaching philosophies, youth sport creativity, and sustainable tendon development. It’s a conversation full of insight, storytelling, and reminders of what truly anchors a lifelong athletic journey: curiosity, joy, and the art of falling in love with movement.

(https://www.just-fly-sports.com/podcast-home/) 0:00 – Early upbringing in Latvia and falling in love with movement 6:18 – Play, curiosity, and environment driven athlete development 14:50 – Injuries, setbacks, and choosing to continue competing 23:40 – Czech training experience and constraints based coaching 33:05 – European versus American development and long term athlete philosophy 45:10 – Games, novelty, and bringing play back into training 59:47 – Specialization mistakes and the importance of multi sport development 1:11:48 – Plyometrics, bounding, and gradual tissue adaptation 1:22:40 – Injury lessons, tendon health, and the value of long term gradual loading Actionable Takeaways 6:18 – Play, curiosity, and environment driven development Reinis explains that his athletic foundation came from unstructured exploration, not early specialization. Let athletes solve problems rather than repeat fixed patterns. Encourage outdoor play and varied surfaces to build natural coordination. Curiosity creates better movers than rigid instruction. 14:50 – Navigating injuries and staying in the sport Reinis shares how setbacks led him to rethink training instead of quitting. Use injuries as a signal to adjust training rather than push through blindly. Keep a competitive outlet during rehab to maintain identity and motivation. Return with smarter progression instead of trying to reclaim old numbers immediately. 23:40 – Constraints based learning from Czech training Reinis describes how training environments shaped movement without heavy cueing. Change the environment before changing the athlete. Use simple tasks and small boundaries to create automatic technical improvements. Let athletes feel solutions instead of chasing perfect positions. 33:05 – European versus American development Reinis contrasts long term models focused on movement quality rather than short term output. Early years should build durability, not just speed and strength metrics. Avoid rushing physical qualities before coordination and play are established. Development is a process of layering, not skipping steps. 45:10 – Bringing games and novelty back into training Reinis highlights how playful constraints improve responsiveness and decision making. Add game based movement to keep athletes adaptive under changing conditions. Use novelty sparingly to reawaken coordination and intent. Reduce scripted drills when athletes stop learning from them. 59:47 – Multi sport value and avoiding early specialization Reinis explains why single sport paths can limit long term performance. Multiple sports expand movement bandwidth and reduce overuse. Delay specialization until athletes have broad coordination skills. Early success does not guarantee long term development. 1:11:48 – Plyometrics and gradual tissue progression Reinis stresses that bounding and plyos require patience and slow tissue adaptation. Progress volume and intensity over seasons, not weeks. Start with low amplitude contacts before higher velocity work. Tendons adapt slower than muscles, so loading must reflect that timeline. 1:22:40 – Tendon health and long term loading approach Reinis shares what he learned from repeated injury cycles. Small, ...

  • 490: Austin Jochum on Engineering an Elite Training Stimulus

    490: Austin Jochum on Engineering an Elite Training Stimulus
    Nov 20 2025
    Today’s guest is Austin Jochum. Austin Jochum is the founder of Jochum Strength, a former All-Conference safety turned performance coach known for playful, movement-rich training. He blends strength, speed, and adaptability to help athletes build real-world capability and enjoy the process. So often, coaches inadvertently play by the formal “rules” of coaching, through substantial instruction, within smaller boxes of training. Gameplay and sport itself are the ultimate example of task-based stimulation, chaos, and problem-solving, and the more we learn from it, the more effective our training can become. In this episode, Austin Jochum and I explore how coaching transforms when you trade rigid cues for play, stimulus, and athlete-driven learning. We dig into why intent and novelty matter, how to “win the day” without chasing constant PRs, and the power of environments that let athletes self-organize. Austin speaks on his recent dive into improving his Olympic lifting, and subsequent improvement in explosive athletic power, along with the masculine and feminine nature of the snatch and clean and jerk, respectively. Finally, Austin also breaks down the JST Olympics—his team-based approach that’s exploding motivation, competition, and performance in the gym.

(https://www.just-fly-sports.com/podcast-home/) 0:00 – Austin’s background, wrestling influence, and early training lens 8:12 – How wrestling shaped his coaching, problem-solving, and creativity 14:30 – Working with movement constraints, unpredictability, and the “maze” idea 22:40 – Why he prioritizes exploration over instruction 31:18 – Building athletic bandwidth through games and environmental design 38:01 – Touch on wrestling in training and contact-oriented movement 45:10 – Heavy rope training, rhythm, and full-body sequencing 52:46 – Hiring coaches and building culture inside his gym 1:01:37 – Athlete intuitiveness, imitation, and imitation-driven learning 1:10:55 – Recovery methods, cold exposure, and principles behind them 1:18:42 – Breathing mechanics, sensory awareness, and relaxation 1:24:52 – Tempo, rhythm, and “feel” in athletic movement 1:30:48 – Coaching philosophy and where Austin is heading next Actionable Takeaways 8:12 – Use problem-solving sports to shape athletic intelligence Wrestling taught Austin to read bodies, adapt instantly, and explore solutions without external cues. Add low-level grappling or tagging games to build instinctive reaction. Favor tasks where athletes solve problems on their own rather than through constant cueing. Let athletes “feel” leverage, pressure, and timing instead of explaining it. 14:30 – Build constraints that shape behavior instead of commanding technique Austin’s “maze” concept uses environment and rules to funnel athletes into better movement patterns. Use boundaries, footwork boxes, or timing rules to nudge athletes into desired solutions. Ask “what would make the athlete naturally move better?” instead of “how do I cue it?” Encourage unpredictable tasks that force athletes to explore and adapt. 22:40 – Exploration outperforms instruction for long-term development Austin finds that athletes learn faster when they discover solutions. Give them space to experiment before layering instruction. Adjust one variable at a time and let athletes reorganize around it. Use questions (“What did you feel? What would you try next?”) to guide reflection. 31:18 – Games expand movement bandwidth Austin uses play-based drills to build coordination, elasticity, and adaptability. Rotate games: tag, dodgeball variations, reactive pursuit, to challenge perception-action loops. Use small-sided tasks to increase decision density without overthinking. Keep the focus on fun: fun increases intent and frees up movement quality. 38:01 – Use wrestling-inspired drills for strength without rigidity Wrestling movements gave Austin strong connective tissue without bulky lifting. Use partner-resistance tasks for whole-body strength and tension awareness. Build isometrics out of wrestling positions for joint integrity. Allow controlled chaos; body contact builds stabilizing capacity. 45:10 – Heavy rope work for rhythm, sequencing, and tissue tolerance Austin relies on heavy rope patterns for global coordination. Use ropes to sync hands, feet, hips, and breath. Program flowing, continuous patterns to teach timing and smooth force transfer. Start with simple rhythms, then build patterns that cross midline. 52:46 – Culture and community determine training success Austin emphasizes hiring ...

    489: Bill Smart on Isometrics, Flywheels, and Elastic Power Development
    Nov 13 2025
    Today’s guest is Bill Smart. Bill is a sport scientist and physical preparation coach specializing in elite fight-sports performance. As the founder of Smarter Performance and the Strength & Conditioning lead for the CORE MMA team, Bill integrates cutting-edge evidence with real-world high-performance systems to enable combat athletes to show up on fight day in optimal physiological condition. Much of the conversation in sports performance hinges on speed and power development, or conditioning, as a stand-alone conversation. Sport itself is dynamic and combines elements of speed, strength, and endurance in a dynamic space. Training should follow the same considerations to be truly alive and effective. In the episode, Bill shares his journey from cycling and rowing to combat sports. He discusses how long isometric holds develop both physical and mental resilience, and their implementation in his programming. The conversation dives into muscle-oxygen dynamics, integrating ISOs with conditioning, and how testing shapes his approach. Bill also explores flywheel eccentrics, fascicle-length development, and why sprinting is a key element for maintaining elastic power in elite fighters.

(https://www.just-fly-sports.com/podcast-home/) Timestamps 0:00 – Bill’s coaching journey and early mentors 6:04 – The importance of movement observation and intuition 11:35 – Why athletes plateau and how to identify limiting factors 20:42 – Strength training principles that actually transfer 30:01 – Using movement variability and play in training 40:36 – Coaching communication and creating connection 52:09 – The role of curiosity and creativity in coaching longevity 1:00:55 – Key lessons from years of coaching experience Actionable Takeaways 6:04 – Movement observation and intuition Bill emphasizes that the best coaches develop a trained eye for movement by observing, not just testing. Watch athletes move in multiple contexts before prescribing anything. Look for how they transition between patterns, not only the end positions. Use video less for judgment and more for curiosity. What is the athlete trying to do? 11:35 – Identifying limiting factors Athletes plateau when coaches overemphasize one metric or capacity while ignoring the real constraint. Look beyond the weight room; technical or psychological factors often drive plateaus. Use minimal testing data to narrow focus rather than justify complexity. Sometimes the limiting factor is overcoaching. Let athletes fail and self-correct. 20:42 – Strength that transfers Transfer happens when strength work complements, not competes with, the sport’s rhythm and intent. Prioritize strength that preserves elasticity and timing rather than just force output. Rotate exercises often enough to keep athletes adaptive, but not so often that they lose rhythm. Load movement patterns, not just muscles. Treat every lift as coordination under resistance. 30:01 – Variability and play in training Bill describes play as a teaching tool that restores creativity and problem-solving in athletes. Use small games, uneven surfaces, or timing constraints to build adaptable movers. Variability should be purposeful. Expand coordination bandwidth without losing technical intent. Schedule “uncoached” time in sessions where athletes explore movement freely. 40:36 – Coaching communication and connection Great coaching depends on trust and empathy before information transfer. Deliver feedback as collaboration, not correction; frame cues as shared problem-solving. Match your communication tone to the athlete's readiness and personality. Be consistent and calm under pressure; emotional stability is contagious. 52:09 – Curiosity and creativity for coaching longevity Curiosity keeps coaching sustainable; creativity prevents burnout. Study outside your lane: music, design, or art can refine pattern recognition. Avoid rigid “systems” that turn coaching into mechanical input-output. Revisit old training ideas with a new lens instead of constantly chasing novelty. 1:00:55 – Key lessons and philosophy Bill’s long-term perspective is about developing people, not just performers. Build a coaching environment where learning continues on both sides. Focus on long-term process rather than short-term validation. Great coaching is about alignment between words, actions, and values. Quotes from Bill Smart “Observation is the beginning of understanding movement. You can’t coach what you don’t actually see.” “If you only measure outputs, you’ll miss what’s driving them.” “Strength is ...

    488: Sam Elsner on Rewiring Athletic Performance and Movement Learning
    Nov 6 2025
    Today’s guest is Sam Elsner. Sam is a former NCAA Division III national champion thrower turned motor learning writer and educator. He’s the author of The Play Advantage and creator of the Substack CALIBRATE, where he explores how humans learn movement through play, perception, and environment design. Sam brings a rare blend of elite athletic experience and deep skill-acquisition insight to help coaches and athletes move beyond drills toward true adaptability and creativity in sport. As athletic performance is largely driven by weight-lifting. It digs into maximal strength and force-related outcomes in such excess that all other elements of athleticism are negated. Skill learning and high velocity movement are the wellspring of sporting success. As such, having a balanced understanding of the training equation is critical for the long-term interest of the athlete. On today’s podcast, Sam and I dive into how athletes truly learn to move. Sam traces his journey from WIAC throws circles to Cal Dietz’s weight room, why a rigid “triphasic for everyone” phase backfired with a soccer team, and how ecological dynamics and a constraints-led lens reshaped his coaching. Together we unpack the strength–skill interplay, 1×20 “slow-cook” gains versus block periodization, the value of autonomous, creative training application. We touch on youth development, culture, and team ecology, plus where pros are experimenting with these ideas. This episode is loaded with both philosophy of training and skill learning, along with practical takeaways in program design. Today’s episode is brought to you by Hammer Strength.

(https://www.just-fly-sports.com/podcast-home/) Timestamps 1:18 - Early training experiences and triphasic background 5:44 - Implementing triphasic as a young coach 11:22 - The failure of rigid block periodization 17:49 - Vertical integration and maintaining all qualities 24:58 - Discovery of the ecological dynamics lens 29:57 - Why skill learning changed his view of strength 35:43 - 1x20 as a slow cooking strength framework 43:15 - Autonomy and stance/position freedom in the weight room 52:38 - Culture, environment, and how athletes learn 1:00:43 - Highlight play examples and perception-action 1:14:23 - Constraint-led models in team sport settings 1:20:55 - Where to find Sam’s work Actionable Takeaways 5:44 - Learning from early programming mistakes Rigid triphasic blocks without speed and skill work led to slower, less adaptable athletes. Keep speed, power, and reactive work present year-round in some capacity. Avoid assuming what works for one context transfers straight across to another. 17:49 - Vertical integration instead of siloed periodization Train multiple physical qualities year-round with shifting emphasis rather than isolating one block at a time. This prevents athletes from losing speed while developing strength, or vice versa. Small doses across the year keep qualities alive and connected. 24:58 - Skill learning must reflect the chaos of sport Sport is unpredictable, not robotic. Training should reflect that uncertainty. Use varied environments, movement options, and constraints instead of perfect reps. Skill emerges from exploration, not memorization. 35:43 - 1x20 for strength that supports skill 1x20 builds strength while leaving room for sprinting, jumping, and skill work. The last few reps in a 1x20 set still hit high effort without excessive nervous system cost. Use stance and tempo variations to match individual structure. 43:15 - Autonomy inside the weight room Allow athletes to choose stance width, bar position, and grip style within a lift. This respects anatomical differences and promotes ownership. Autonomy increases buy-in and self-organization. 52:38 - Culture shapes movement outcomes The environment athletes train in determines how they move and learn. If culture only rewards load and intensity, adaptability is lost. Design environments that reward exploration and awareness, not just output. 1:00:43 - Highlight plays reflect attunement, not force Elite athletic feats arise from pattern recognition and perception-action coupling. You cannot coach highlight movement through force metrics alone. Create rich movement histories rather than perfecting single patterns. Quotes "Sport is chaotic and uncertain. If your training isn’t reflecting that, you’re training for something else." "Strength is only useful if you can actually express it in the environment that matters." "1x20 gave me room to train speed and jumping instead of spending all my adaptation on heavy lifting." "We lose athleticism when we isolate qualities instead of integrating them." "Autonomy in the weight room lets athletes ...

    487: Ben Simons on Speed Training and the Art of Explosive Longevity
    Oct 30 2025
    Today’s guest is Ben Simons. Ben is a British performance coach and two-time Olympic bobsledder with a background in sprinting and sports science. A former World Cup gold medallist, he’s now focused on helping athletes develop speed, power, and coordination through evidence-based, real-world training methods. Ben blends biomechanics, motor learning, and nervous-system training to build explosive, adaptable athletes. Many speed training topics and conversations focus exclusively on the most stimulating possible methods; fewer get into individual factors, athlete adaptability, and how that speed and power training evolves with the needs of the athlete. On today’s show, Ben and I discuss asymmetry, rhythm, and “aliveness” in sprint and power development. We explore when to let unique mechanics—like Byanda Wlaza’s galloping stride—run their course versus coaching toward a technical model. Ben gets into the general speed training lessons he gained from bobsled, and shares why he now favors yielding isometrics, unilateral strength, and med ball throws over heavy lifts, emphasizing longevity, reflexive strength, and movement variability. We finish with how curvilinear sprints, pool work, and playful, multidirectional movement help athletes stay reactive, adaptable, and pain-free.

(https://www.just-fly-sports.com/podcast-home/) Timestamps 0:00 – Asymmetry, gallop running, and what to do with extremes 12:25 – Air-time vs ground work: why the stuff in the air transfers to sprinting 16:08 – From long jump and 4x100 to bobsled trials and the push track 19:57 – Retirement, coming back, and the management needed for longevity 24:04 – Achilles management, playing sport, and the power of movement variety 31:09 – Practical coaching advice: get people back into the sport they love 41:31 – Curvilinear sprints, feeling safe, and bringing play into rehab 45:53 – How bobsled pushing changed Ben’s acceleration and posterior chain 52:28 – Hamstring training, velocity, and the limits of eccentric volume 59:46 – Practical tools: tank sleds, prowlers, glute-ham machines, and Zurcher split squats 1:08:19 – Why Ben minimized compound max lifts and what he uses now 1:24:46 – Programming for mature athletes: living off the strength bank and using yield isometrics Actionable Takeaways 0:00 – Asymmetry, gallop running, and what to do with extremes Ben discusses the gallop-style sprint and whether to coach it out or keep it in the bandwidth. Use a technical benchmark as your reference, then assess the athlete’s bandwidth before changing form. If an athlete still performs well, test before adjusting — not every asymmetry needs fixing. Sled pushing can exaggerate patterns, so train sled and unweighted sprints separately for balance. 12:25 – Air-time vs ground work: why the stuff in the air transfers to sprinting Ben highlights the value of airborne drills and how isolating sides changes learning. Mix air-time drills (A-skips, dribbles) with reflexive work that reinforces limb exchange. Use isolating drills to refine control, then transition back to dynamic, reciprocal actions. Treat drills as tools to build feel, not techniques to be perfected. 16:08 – From long jump and 4x100 to bobsled trials and the push track Ben explains how testing funneled him into bobsled and what carried over from track. Identify transferable metrics (sprint speed, jumps) when guiding athletes into new sports. Plan gradual body composition changes to meet the new sport’s demands. Treat push-track practice as a specific development tool, not just novelty work. 19:57 – Retirement, coming back, and the management needed for longevity After retiring and returning, Ben focused less on output and more on resilience. Manage exposure and reduce cumulative max-strength volume. Replace some heavy lifts with unilateral, metabolic, and yielding isometric work. Use program variety, low-impact options, and smart recovery methods to extend career length. 24:04 – Achilles management, playing sport, and the power of movement variety Ben credits playful movement and variety for helping tendon and joint health. Add small doses of games (tennis, soccer, basketball) to reintroduce variability. Use pool work or hydro drills for recovery and postural reset. Mix in curvilinear or lateral movement constraints to keep tissues adapting. 31:09 – Practical coaching advice: get people back into the sport they love For long-term motivation, Ben recommends bringing fun back into training. Encourage clients to play their favorite childhood sport once a week. Adjust strength or ...

    486: Cody Hughes on Principles of Athlete Centered Power Development
    Oct 23 2025
    Today’s guest is Cody Hughes. Cody is a strength and performance coach at Farm & Forge in Nashville, blending over a decade of collegiate and private-sector experience into a practical, athlete-centered approach. His work bridges foundational movement with modern tools like VBT and GPS tracking, always anchored by the belief that health drives performance. With the rising influence of technology in training, it can become more difficult to look clearly at the core facets of athletic force production, as well as how to optimally use technology to fill gaps, inform decisions, and even motivate groups. On today’s episode, Cody traces his shift from heavy-loading bias to a performance lens built on force management, eccentric RFD, and training that actually reflects sport. We unpack depth drops vs. “snapdowns,” why rigid “landing mechanics” miss the mark, and how movement literacy, variability, and velocity drive speed and durability. On the tech side, we get into velocity-based training (VBT) as a feedback and motivation tool, using it to gamify effort and auto-regulate load, and knowing when to remove the numbers to protect recovery and intent. Leaderboards, incentives, and smart stimulus design all matter, but Cody keeps it clear that data supports the human element that produces real power.

(https://www.just-fly-sports.com/podcast-home/) Timestamps 0:00 – Early lifting story and the hip replacement turning point 5:31 – Coaching development, biases, and error-driven learning 19:29 – The snapdown debate: context, progressions, and purpose 25:44 – What eccentric RFD tells us about athletic durability 30:42 – Strength as expression: assessments and force-plate logic 42:31 – Movement literacy and using competitive, decision-rich drills 49:30 – VBT explained: feedback, governors, and gamification 56:50 – When to hide feedback: elite athletes and psychological load 1:01:35 – Where VBT shines: youth and early training ages 1:25:28 – Wrap up and where to find Cody Actionable Takeaways 0:00 – Early lifting story and the hip replacement turning point. Cody’s early heavy-loading bias led to a total hip replacement and changed his training philosophy toward stability and movement quality. Reassess program priorities after a major injury: shift emphasis from maximal compressive loading to single-leg work, mobility, and stability. Use your injury story as a guardrail: design training that preserves life-long movement and allows play with family. Teach athletes the why: heavy strength is useful, but it must be paired with tissue resilience and mobility to avoid long-term breakdown. 5:31 – Coaching development, biases, and error-driven learning. Cody stresses that coaching wisdom grows from coaching people, making mistakes, and combining mentorship with hands-on experience. Get "skin in the game": coach real athletes and collect mistakes that refine your practice, not just textbook theory. Seek mentorship and internships to accelerate learning while still accepting the value of self-discovery. Avoid premature certainty: test provocative ideas and be ready to change your mind when evidence or outcomes demand it. 19:29 – The snapdown debate: context, progressions, and purpose. Snapdowns can be either a motor-learning tool for hinge/positioning or a low-value, non-stimulating ritual depending on context. Use snapdowns as a micro-dose progression: for young athletes, combine unweighting, pelvic control, and velocity to teach hinge and pretension. Do not use snapdowns as a one-size-fits-all landing mechanic; if the only goal is "landing mechanics," favor exposing tissues to a range of velocities, angles, and vectors instead. If snapdowns are used with elite athletes, ensure they serve an explicit force- or RFD-related progression, not just a warm-up checkbox. 25:44 – What eccentric RFD tells us about athletic durability. Eccentric rate of force development strongly correlates with sports performance and longevity; capacity to handle rapid braking is crucial. Include progressive eccentric exposures (depth drops, drop jumps) to train braking RFD, using force metrics when possible. Teach athletes both options: hard, stiff contacts for quick reactivity or yielding strategies for impulse extension depending on the task. Combine eccentric work with decision-making drills so athletes learn to anticipate and pretense contact in sport contexts. 30:42 – Strength as expression: assessments and force-plate logic. Strength is task-dependent expression; force plates can reveal propulsive power, braking power, and RFD in meaningful ways....

    485: James de Lacey on Rhythm, Reactivity, and the Art of Athletic Power
    Oct 16 2025
    Today’s guest is James de Lacey. James is a professional strength and conditioning coach and the founder of Sweet Science of Fighting, a leading platform for combat sports performance. He has coached in professional rugby leagues across New Zealand, Europe, and the United States, and has trained athletes in MMA, boxing, Muay Thai, and BJJ. Through Sweet Science of Fighting, he delivers evidence-based programs and education for fighters and coaches worldwide. Strength training for athleticism typically focuses on sets, reps, and general forces, but rarely gets into aliveness and skill management of the resistance itself. The former is great for building basic physical competencies, but in integrating the latter, we can breathe more life into a performance program. On today’s show, we dive into James' approach to building athletic strength and power across multiple mediums. We explore how Olympic lifting, especially pull variations, connects to real sport actions, and how striking and collision sports highlight the importance of timing, rigidity, and effective mass. We also break down resistance methods like oscillatory work, flywheels, and accentuated eccentrics, focusing on their alive, reactive qualities rather than just load. These principles carry into speed and power training, including plyometrics and sprinting, with rhythm and movement quality as a central theme. The episode makes strong connections between field sports and combat sports, showing how momentum, relaxation, and rigidity at impact shape performance.

(https://www.just-fly-sports.com/podcast-home/) Timestamps 0:56 - Olympic Lifting Philosophy and Sport-Specific Implementation 4:26 - The Role of Bar Flex and Slack in Block Pulls vs. Rack Pulls 7:03 - High Block Work for Impulse and Technical Refinement 12:22 - Oscillatory Training and the Limits of Maximal Strength 24:49 - Upper/Lower Body Dissociation for Fluid Movement and Game Speed 52:25 - Controlled Eccentric Overload using Flywheel Technology Actionable Takeaways 0:56 - Olympic Lifting Philosophy and Sport-Specific Implementation Prioritize Pull Variations: Use variations like the high pull, especially in combat sports (grapplers), to strengthen the upper back and facilitate violent, vertical hip extension. This is useful for actions like a mat return. Select Snatch over Clean: Choose snatch variations (e.g., power snatch from the hip/hang) over the clean for general athletes because the front rack position is often too difficult, making the snatch easier to learn. Match Lift to Resource/Context: Recognize that the implementation of Olympic lifts in a team setting is often constrained by equipment (e.g., only two barbells for a team) and the athlete's level. 4:26 - The Role of Bar Flex and Slack in Block Pulls vs. Rack Pulls Understand Sensory Differences: Recognize that pulling from blocks feels different than pulling from a power rack. Blocks hold the plates, allowing for "slack" and "flex" in the bar, similar to a deadlift bar. Avoid Dead Weight: Pulling from a rack holds the bar and removes the flex, creating a "dead weight" stimulus, which makes the lift harder and limits the use of bar properties to set positions. 7:03 - High Block Work for Impulse and Technical Refinement Train for Time Constraints: Utilize high block work to force athletes to generate high impulse in very short time frames, mirroring the time constraints often encountered in sport. Force Pull-Under Technique: High blocks are a beneficial constraint that forces the athlete to actively "pull themselves under" the bar, addressing a common technical flaw where athletes dive under instead of finishing the pull. Facilitate Speed via Relaxation: Understand that successful Olympic lifting requires a "pseudo activation relaxation kind of thing," where relaxation facilitates the speed needed to pull under the bar. 12:22 - Oscillatory Training and the Limits of Maximal Strength Use Oscillatory Isometrics: Implement oscillatory or pulse-style isometric exercises, such as a pulsing single-leg glute ham raise isometric, for specific adaptations (e.g., in-season hamstring work). Re-evaluate Max Strength Bias: Understand that an over-emphasis on maximal strength may not transfer to improved power in short time frames. Research suggests that "relaxation kinetics" can be negatively adapted by heavy strength training alone, causing athletes to "break earlier" in fast, cyclical actions. Prescribe by Sport Demands: Group athletes by position or sport needs: grapplers need high force; strikers need high velocity; rugby backs need speed; tight five need strength; ...

    484: Manuel Buitrago on Olympic Lifting, Pressure Mechanics and Explosive Athleticism
    Oct 9 2025
    Today’s guest is Manuel Buitrago. Manuel is a PhD, along with being the founder and director of MaStrength, a global education brand dedicated to authentic Chinese weightlifting. Since launching MaStrength in 2014, he’s taught 100+ seminars worldwide, authored Chinese Weightlifting: A Visual Guide to Technique and Chinese Weightlifting: Technical Mastery & Training There are many misconceptions in the world of strength training, especially as the lens of a skeletal pressure-based view is not included in modern training systems. When skeletal pressure dynamics are understood, it allows us to see why athletes prefer particular variations of lifts, how and why they fail lifts, and what aspects of the lifts themselves lead to better athletic outcomes. On today’s episode, Manuel speaks on the practicalities of weightlifting and how it carries over to sport. He compares powerlifting and Olympic lifting from a technique and transfer standpoint, and gets into how body shapes, breathing, and set-ups affect a lift. Manuel also touches on connective tissue and why it matters for performance and durability. From this episode, you’ll learn concepts about the Olympic and powerlifts that can not only improve lifting performance but also facilitate a better transfer to athleticism and movement ability.

Use cross-sport curiosity: explore other lifting cultures to discover training cues that fit your athlete. Test new lifts with low ego loads to learn the feeling before programming heavy progressions. When an approach resonates (Manuel saw this in video footage), lean into learning it systematically rather than chasing trends. 3:34 - First Olympic lifting exposure via IronMind footage and Pyrs Dimas Seeing training hall footage made manual learning possible; video can reveal consistent patterns across a team. Use curated training footage to spot systematic cues you can trial in the gym. Compare multiple athletes in the same system to find the shared principles, not the outlier quirks. Trial small protocol elements from footage (timing, shapes, sequencing) on yourself or a pilot athlete before scaling. 5:40 - The Chinese team’s systematic approach that sparked the study abroad Manuel noticed consistent shapes and timing in the Chinese footage that contrasted with other teams’ variety. When observing multiple athletes, note common positions and tempo as signals of a system you can emulate. If a system looks consistent and repeatable, consider immersive study (courses, short placements) to learn its language. Use language and cultural learning to communicate directly with athletes and coaches when studying foreign systems. 9:30 - Breathing, shapes, and the funnel concept for lifting Manuel stresses creating a funnel-shaped torso from the start position - compressed lower torso plus expanded upper torso - to bias upward movement. Teach athletes to compress the abs first, then allocate air to the upper torso so chest and mid-back expand; this creates an upward gradient. Practice the shape unloaded: stand, exhale to compress lower abs, then fill front and back of upper torso so the mid-back expands. Repeat until the cue is reliable. Avoid powerlifting-style breathing in the start position (squeezing top while pushing belly against the belt) when the goal is quick upward reversal. 26:15 - Bottom-up squats: why weightlifting squats differ from powerlifting squats Weightlifting squats are usually “bottom-up” because the lift catches are unweighted while the bar rises; powerlifting squats tend to be “top-down”. Program bottom-up variations (Andersons, pin squats, bottom-position work) to train the specific rebound and reversal ...
