このエピソードについて
In this episode, Anthony breaks down what zone 2 training actually develops beneath the surface and why it matters for strength athletes, hybrid competitors, and everyday lifters. He explains the physiology behind aerobic adaptation, how to accurately find the right intensity, how to avoid the classic interference trap, and how to integrate low intensity conditioning without compromising strength. The focus is on precision, sustainability, and building an engine that supports performance long term.
