Welcome to THE HEAVY DUTY NATION by Markus Reinhardt — the only community built on the original High-Intensity Training legacy. Trained directly by Mike Mentzer, I carry on the real system that transforms physiques and mindsets with precision and logic — not hype. Inside, you’ll get my complete HIT courses, exclusive eBooks, live weekly Q&As, and direct access to me. Now with new HD training and instructional videos added weekly, you’ll see exactly how Heavy Duty is meant to be performed — rep by rep, set by set. No BS, no wasted time — just pure Mentzer-style efficiency. If you’re tired of confusion and cookie-cutter programs, this is where serious lifters come to learn Heavy Duty the right way — scientifically, rationally, and brutally effective.
