I’ve had various 3 day splits recently, and would like to open my mind to doing 4 day splits or perhaps something that "doesn’t care what day of the week it is?
What is your favorite split, including muscles worked?
Day 1: Chest/legs
Day 2: shoulders/bi
Day 3: Back/tri
Day 4: other activity
Day 5: Start over
Finish every other work out with some stomach (oops! I mean “core”)
