push/pull is only the new way of saying chest/shoulders/tris & back bis
Yes, but there's a myriad of different ways you can exercise each group and I tried Scot Herman's 'Push A' routine and it was very cleverly laid out. You'd probably have to experience it to understand, but he gives the exercises, the sets and the rest time between sets and it 'really hits the spot'.
For example when you've already really worked your chest, shoulders and tricep hard, he finishes this portion off with a 'low-to-high cable fly'. Because there's no tricep involved, it means you're not limited by this muscle. And restricted by only 30 seconds rest it means the weight is low, volume is high, and it just smashes your already tired pecs.
I just thought it was very cleverly designed.
