Introduction When I first started lifting weights as a teenager, I had one goal: to put on weight. I had just turned 15, and the need to bulk up felt urgent. During my birthday party, a few uninvited guys, about my age, gatecrashed the event. We asked them to leave, but one of them—who was … Read more

10 Scientific Studies That Changed My Mind About Strength and Hypertrophy Training

Studying the science behind strength and hypertrophy.

Studying the Science Behind Strength and Hypertrophy For years, I adhered to traditional methods of building strength and muscle—lifting heavy, focusing on progressive overload, and keeping things simple. While these fundamentals remain valuable, recent scientific research has refined my approach, adding layers of complexity that I hadn’t fully appreciated. In this article, I’ll discuss 10 … Read more
