    496: Dustin Oranchuk on Isometrics, Force Production and Elastic Performance
    Jan 1 2026
    Today’s guest is Dustin Oranchuk, Ph.D. Dustin is a sport scientist focused on sprinting biomechanics, speed development, and force production. Known for blending research with practical coaching insight, his work explores how isometrics, elasticity, and coordination shape high-performance sprinting and athletic movement. Isometric training is one of the “original” forms of strength training, and in the modern day has become one of the most popular areas of discussion and training methodology. Although the practice has exploded, it often lacks an understanding of physiology of adaptation with various methods. In this episode, Dustin explores the evolving world of isometric training, including the origins of isometrics. We discuss differences between pushing and holding contractions, tendon and neural adaptations, and modern applications in performance, rehab, and longevity. The conversation also dives into eccentric quasi-isometrics (EQIs), motivation and measurement challenges, and how coaches can intelligently integrate isometrics alongside plyometrics and traditional strength work.

Early isometric systems emphasized position specific strength over movement. Modern usage has expanded beyond barbell sports into rehab and longevity. 8:38 Modern Applications of Isometrics Isometrics are now widely used to “own positions” across joint angles. Longer duration holds are frequently used for tissue health and rehab. Training intent has shifted from peak strength toward durability and resilience. 9:52 Neural vs. Morphological Adaptations Short range, position specific isometrics bias neural intent and coordination. Long muscle length isometrics bias hypertrophy and tendon adaptation. Choose isometric type based on whether the goal is performance transfer or tissue change. 15:45 The Importance of Long Holds Tendons require relatively high intensity to meaningfully adapt. Long holds help reveal side to side asymmetries and control deficits. Extended holds build tolerance and confidence in vulnerable joint positions. 19:42 Combining Isometrics and Plyometrics Pairing isometrics and plyometrics can produce modest additive benefits. Combining methods may reduce fatigue compared to doing each alone. The interaction may enhance effort quality rather than purely physiological output. 39:22 Exploring Eccentric Quasi Isometrics EQIs combine a maximal hold followed by forced eccentric lengthening. They accumulate large time under tension and eccentric impulse. EQIs are powerful but mentally taxing and difficult to sustain long term. 47:10 Periodization and Isometric Training Use longer, lower intensity holds earlier in the offseason. Progress toward shorter, higher intensity, position specific isometrics near competition. Post game isometrics can support recovery without additional joint stress. 1:05:48 Future Research Directions Measurement technology has driven the resurgence of isometrics. Push versus hold distinctions are becoming a key research focus. Future work aims to clarify muscle and tendon behavior during isometric intent. 1:13:00 Closing Thoughts and Reflections Consistency with foundational exercises drives long term progress. Isometrics are tools, not replacements for dynamic training. Coaches should match the method to the goal, not the trend. Quotes from Dustin Oranchuk “Tendons tend to need a certain threshold of intensity to get meaningful adaptations.” “The maximal amount of force you can push is almost always more than what you can hold.” “Isometrics let you own positions rather than just pass through them.” “Long holds are a great diagnostic tool for finding asymmetries.” “EQIs are effective, but they are very hard to push hard and regularly.” “Use the best tool for the job rather than trying to blend everything together.” “Consistency beats constantly reinventing your training approach.” “Isometrics compress joint motion so other systems can recover and adapt.” “Intent matters just as much as the muscle action...

  • 495: Kevin Secours on Rituals of Strength and Movement

    495: Kevin Secours on Rituals of Strength and Movement
    Dec 24 2025
    Today’s guest is Kevin Secours. Kevin is a veteran martial arts coach, author, and former security professional with decades of experience across Japanese Jiu-Jitsu, Karate, and Russian Systema. Holding five black belts (including an 8th-dan), Kevin has worked extensively in real-world contexts while also teaching meditation, solo training, and strength rituals. He is the author of Rituals of Strength and Unconstrained, and is known for blending martial tradition, modern training theory, psychology, and philosophical inquiry into human development and resilience The conditioning and tempering of the body in striking sports can draw interesting parallels to collisions needed in jumping, sprinting and landing activities. We can also draw many lessons and ideas from the exercise tradition that goes back centuries with martial arts practice. By understanding combat training disciplines, we can draw out universal application for general movement and performance. In this episode, we explore the deeper purpose of physical training through martial arts and sport performance. Kevin reflects on early experiences with body hardening, cold exposure, and Zen-influenced practice, examining where such methods build resilience and where they become self-destructive. Drawing parallels to sprinting, jumping, and strength training, we discuss collisions, long isometric holds, ritualized discomfort, and fatigue as tools for cultivating awareness, reducing excess tension, and supporting longevity.

Training should serve health and preparedness, not destroy the body you are trying to protect. Exposure must be progressive and intentional, not reckless. Body tension, trauma, and reading the athlete Chronic tension often reflects psychological history, not just physical limitations. Coaches should first understand an athlete’s motive for training. Creating a safe and inclusive environment allows tension to unwind. Exhaustion can reveal new movement options and reduce overthinking. Isometrics, Soviet methods, and slow strength Long isometric holds build physical strength and mental resilience. Slow strength exposes weak links that fast movement can hide. Discomfort creates space for reflection and adaptability. Training methods were shaped by harsher living conditions and necessity. Journaling, drawing, and learning through reflection Writing and sketching reinforce learning more deeply than words alone. Stick figures and simple drawings improve memory and understanding. Documentation is a form of legacy and long term learning. Mindset, adaptability, and mental speed Adaptability in movement reflects adaptability in thinking. Exposure to opposing viewpoints builds cognitive flexibility. Speed is as much mental as it is physical. Ego and rigid beliefs limit learning and performance. Representativeness, ritual, and resilience Not all training must look like competition to have value. Ritual builds consistency and meaning in training. Resilience is a universal quality that transfers across contexts. Training should include experiences where the athlete loses and adapts. Simplify versus deconstruct in training Simplify first to preserve the integrity of the whole movement. Deconstruct only when specific limitations appear. Always return to full movement patterns after isolation. End sessions with success to reinforce confidence. Microdosing discomfort and daily resilience Small daily challenges build long term mental toughness. Discomfort activates the neural centers tied to willpower. Ritualized discomfort is more effective than occasional extremes. Resilience can be trained deliberately and safely. Comfort seeking and modern training challenges Humans naturally seek comfort when it is available. Modern environments require intentional exposure to challenge. Training should balance safety, stress, and adaptability. Long term growth comes from controlled adversity, not avoidance. Quotes from Kevin Secours “Motive matters ...

  • 494: Quintin Torres on Reactive Strength and Applied Power Development

    494: Quintin Torres on Reactive Strength and Applied Power Development
    Dec 18 2025
    Today’s guest is Quintin Torres, a strength and performance coach specializing in Marinovich/Heus inspired training methods. With a background in martial arts, Quintin focuses on movement quality, coordination, and individualized methods that help athletes build strength that truly transfers to sport. So often in athletic development, it is only the “hard” or easily quantifiable qualities that we look to develop. Although these are vital, sport itself (even output sports) live “in between the cracks” of maximal outputs, and then movement quality. Training rarely looks to infuse a full spectrum of athletic qualities, yet programming such as that put forth by Marv Marinovich years ago, does capture many of these dynamics. On today’s show, Quintin and I explore the Marinovich nervous system training philosophy, contrasting “soft” qualities like reactivity, rhythm, coordination, and perception with traditional hard metrics such as max strength. We discuss why MMA has embraced these methods, the limits of barbell-centric programming, and the importance of observation, experimentation, and individualized coaching. The conversation emphasizes training transfer to sport, creativity, and maintaining athlete adaptability, longevity, and engagement beyond chasing isolated numbers.

(https://www.just-fly-sports.com/podcast-home/) Timestamps 0:00 – Quintin’s background and entry into nervous system training 6:18 – Why Marinovich methods resonate in MMA 10:04 – Soft qualities versus hard qualities in performance 16:11 – Assessment driven training and athlete context 27:05 – One on one coaching versus group models 31:41 – Training quality, group size, and real world constraints 40:12 – Foot strength, barefoot work, and bottom up thinking 1:13:09 – Strength without compression and alternative tools 1:25:55 – Manual resistance and simple coaching tools 1:27:41 – Teaching, sharing, and coaching philosophy Actionable Takeaways Nervous system training priorities Train soft qualities like rhythm, timing, coordination, and fluidity with the same intent as maximal strength. Recognize that many performance qualities cannot be easily measured, but still decide outcomes in sport. Do not confuse testing well in the weight room with performing well in competition. Why MMA accelerates innovation High consequences in MMA force athletes and coaches to evaluate training effectiveness honestly. One on one competition allows clearer cause and effect between training and performance. Customization is easier when the athlete’s output is fully visible and isolated. Assessment over templates Let observable movement qualities guide training choices rather than fixed programs. Consider genetic tendencies such as stiffness, elasticity, and coordination when designing training. Adjust tools and methods to the athlete instead of forcing athletes into a system. Soft and hard qualities integration Maximal strength still matters, but it should not destroy elasticity or coordination. Avoid becoming overly concentric dominant and losing reactive qualities. Balance force production with tendon health and nervous system adaptability. Group training realities Large group settings limit how much individual correction is possible. Use simple movements and constraints when training many athletes at once. Accept logistical realities while still trying to preserve movement quality. Foot and ground based training Treat the foot as a strong and adaptable structure, not a fragile one. Use harder surfaces and direct loading to stimulate neural input from the ground up. Understand that the feet heavily influence the nervous system and movement outcomes. Alternative strength tools Use flywheels, isokinetic tools, and manual resistance to reduce compressive stress. Achieve high neural drive without excessive spinal loading. Match resistance dynamically to the athlete’s output. Manual resistance and coaching feel Hands and simple tools can outperform expensive machines in many cases. Manual resistance allows precise matching of effort and intent. Coaching feel and feedback are critical skills, not outdated practices. Quotes from Quintin Torres “The primary difference is we prioritize the development of soft qualities just as much as hard qualities.” “We do not need you better at training. We need you better at your sport.” “Barbell does not equal maximal strength. It is just one tool on the force velocity curve.” “As the quantity of athletes goes down, the quality of training can go up.” “Your feet are not fragile. They are designed to take abuse.” “There is no strength machine better than your own hands.” “...
