In this episode, we're joined by Dr. Kristi Charish and Dr. Christle Guevarra for a deep dive into fitness and nutrition myths in Jiu-Jitsu! Kristi & Christle explore how bad information spreads, the role of genetics in performance, and why aspiring athletes often fail when trying to do everything at once. They break down key misconceptions around supplements, weight cutting, and performance-enhancing drugs, while also addressing sensitive but crucial topics like Ozempic, hormone therapy, and perimenopause.

This week we're joined by Niamh Bryn, owner of Snowblind BJJ in Seattle! In this episode, Niamh explores the versatility and depth of the arm drag, and why it's more than just a beginner move. We explain its role as an opening salvo to create reactions, off-balances, and angles rather than an all-or-nothing attempt at taking the back.

This week, we're joined again by “Doctor Kickass” Mike Piekarski: physiotherapist, BJJ black belt, online course creator, and instructor! In this episode, Mike discusses injury mitigation, or “prehab,” for grapplers. We explore how injuries commonly occur in Jiu-Jitsu through joint locks, scrambles, takedowns, and ego-driven decisions, and emphasize the importance of situational awareness, tapping culture, and coach-led environments that normalize safety.
