I am considering changing my split routine as well as reducing the # of exercises that I do per muscle group. I currently have a four day split: Chest+Front Shoulders / Back+Shoulders+Traps / Arms / Legs and typically do 4-5 exercises per muscle group (Traps and Shoulders would count as one muscle group here divided over two days). Which three day split is better - P/P/L or C+B/L/S+A - if a three day split would be better at all? Thanks for any and all advice...
