Why do some guys look like they were built for bodybuilding, and others don’t, no matter how hard they train?
The answer is muscle insertions.
In this video, Professor Mass breaks down every major muscle group — Biceps, Abs, Lats, Quads, Calves, Forearms, Chest, and Triceps — and explains exactly how insertion points determine your genetic ceiling.
Good insertions vs bad insertions. What they look like. Who has them. And what you can actually do about it.
