The Heavy Duty Training Program

12 Weeks of Maximum Growth, Minimum Volume

The Heavy Duty Training Program is the modern evolution of Mike Mentzer’s high-intensity philosophy, rebuilt from the ground up using today’s sports science and training data. It’s a complete 12-week system designed for lifters who want to do less but grow more.

This program cuts out the noise. Every set, rep, and rest period has a purpose. You’ll learn how to train at true muscular intensity, manage recovery with precision, and measure real progress without the guesswork.

Inside you’ll get two components that work together seamlessly:

1. The Heavy Duty Training Guide
A full 87-page educational guide written by the Heavy Duty Training Team. It covers everything from Mentzer’s principles and biomechanics to recovery, nutrition, and psychological focus. Each chapter blends old-school logic with modern research, showing exactly how and why Heavy Duty Training works. Backed by over twenty peer-reviewed studies and written in a way that you'll want to read.

2. The HDT Master PRO Tracker
Your data-driven training partner. The tracker automatically calculates your estimated 1RM, intensity scores, and weekly trends so you can see exactly how you’re progressing. Just log your weight, reps, and RIR, everything else auto-updates for you. The sheet includes all 12 weeks of push, pull, and leg sessions, with built-in performance flags and weekly summaries.

This isn’t a high-volume routine. It’s a test of focus, accuracy, and intent.
If you train hard, recover properly, and track honestly, this system will reward you with the best strength and size gains of your life.
