And every time, I want to … Read more

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

by
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
