Today, we're joined by none other than Alex Sterner — a Brazilian Jiu-Jitsu black belt under the legendary Andre Galvao, and one of the world’s top strength and conditioning coaches in the sport of BJJ. Alex is the co-founder and head coach at Electrum Performance, the official strength and conditioning team behind elite grapplers like the Atos squad, who’ve racked up multiple IBJJF World Titles.
With a Bachelor’s in Kinesiology from the University of Connecticut and certifications as a CSCS and USA Weightlifting coach, Alex blends cutting-edge science with real-world experience, training some of the best in the game — including Andre Galvao, JT Torres, and Lucas Barbosa.
In this episode, Alex breaks down how to optimise muscle growth, enhance athletic performance, and prepare your body for the unique demands of competitive Brazilian Jiu-Jitsu. He also dives into his powerful philosophy of “movement optimism” — a mindset shift that challenges traditional views on pain, posture, and rehab.
