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.
