With the BEGINNER training you’ll train 3 times a week & build muscle faster than an “intermediate” training 5x a week.
Muscle only “grows” when it’s recovering, after you train it! Beginners recover slower than intermediates, & need less training to build more. Optimizing your recovery so max-growth occurs is a critical aspect of this training. As are the exercises! Every exercise you do is compound, builds muscle in multiple places per rep, & is progressively overloaded weekly.
