HE’S ONE OF the most respected fitness minds on the internet, but Mike Israetel isn’t just sitting behind a microphone and firing off hot takes about everything from celebrity workout plans to new studies in the field of exercise science from his Renaissance Periodization YouTube channel. Israetel—or Dr. Mike, given his PhD in sport science—gets after it in the gym, too. He’s a competitive bodybuilder who practices what he preaches.
“My general philosophy when it comes to training is to training is to maximize the effectiveness of the training and minimize the downsides,” he says. How does he do that? Focusing on form and hard training in the right rep ranges while also reducing fatigue, muscle stress, and overall time spent training.
Israetel’s current fitness goal is to build up his shoulders and arms to improve his overall physique. “If my shoulders and arms were bigger, it would lead to more happiness, I think,” he quips. “Or at least better results in bodybuilding competitions.”
