Heavy duty

In 'Heavy Duty,' Mike Mentzer outlines his high-intensity training philosophy, which contrasts sharply with the high-volume training methods popular during his time.

Mentzer advocates for training to failure with minimal sets and reps, emphasizing the importance of intensity over volume.

He draws on the influence of Arthur Jones, the inventor of Nautilus equipment, and his own experiences as a competitive bodybuilder.

The book provides detailed workout routines, including push, pull, and legs splits, and stresses the critical role of recovery and progressive overload in muscle growth and strength development.
