I’ve been doing the following for about 6 months now:
Day 1: Back/Biceps
Day 2: Chest/Triceps
OFF
Day 3: Back/Biceps
Day 4: Chest/Triceps
OFF
OFF
PLUS Abs twice a week, and legs almost never (I’ve been tagging along with someone who does this, but I sense that I could be doing better things, especially legs.)
I think I might want to do this plan:
Day 1: Shoulders (S/L/R Deltoids & Traps) & Abs
Day 2: Legs (Quads/Hams) and Forearms
30 Min Low Intensity Cardio
Day 3: Chest & Triceps & Abs
Day 4: Back & Biceps & Calves
Why don’t you just find a program designed by one of the authors on this site and follow that?
Honestly, I think that is is garbage. Besides that fact that you have 3 upper body days and 1 leg day, I don’t think that splits can be effectively utilized with just 4 days a week.
