Push, pull and legs is a very simple, yet effective training split for anyone, ranging from those picking up their first barbell to hardened gym veterans. Push workouts include chest, shoulders and triceps. Pull workouts take care of back and biceps. While leg workouts cover quads, hamstrings and calves.The reason it works so well is that it places more emphasis on multi-joint compound exercises than on isolation-based exercises. ~ Berceste
