I have a question regarding bodyweight training. Now I usually train with a 4 day split and have gotten great reults. However my brother sticks to body weight training. All he does are pull up variations, push up variations, body squats, and ab work. I was wondering how is it that he still has a good amount a growth in muscles he does not work like calves and shoulders, does that body just want to stay about the same size all over?
Maybe it is he routine, he has no real set/rep scheme, all he does is try to reach a certain target number of reps. For example 250 push, 250 pull ups, and 500 squats with some ab work in 1-1 1/2 hrs.
