Biography of Mike Israetel

Mike Israetel, born Michael Israetel, is a fitness expert, sports scientist, and educator known for his deep knowledge of training theory and practical application. He’s a co-founder of Renaissance Periodization (RP Strength), a company that’s become a go-to source for evidence-based fitness and nutrition programs. His work spans multiple areas including bodybuilding, strength training, and martial arts, especially Brazilian Jiu-Jitsu, where he holds a black belt.

Before he became a full-time fitness educator, Mike taught at the college level, sharing his passion for exercise science with students. That academic background gives him a unique edge in the fitness space, where so much advice is based on anecdote or outdated theory. Mike, on the other hand, builds everything he teaches on solid, peer-reviewed science.

He’s also a competitive bodybuilder himself, which gives him street cred in more ways than one. He’s not just a guy in a lab coat—he’s in the trenches, testing his theories in real life. That’s probably why his advice feels so practical and doable, even for regular folks trying to stay fit and healthy.
