How to use it

For size, each muscle needs a real stimulus about every 72 hours, so at least twice a week. Split it any way you like (full body twice, upper/lower, a split): the rule is the frequency, not the method. Each working set ends 1-3 reps from failure.

How sure we are

S Evidence: strong. Large trials or many studies, pointing the same way.

E Evidence: built from practice. What works for coaches and practitioners. Labelled that way.
