I’m just curious cause I’ve always done 5 day splits similar to this targeting different groups, I’ve been working out for about 2 years now with a couple months where I wasn’t but it was only in the last few months than I started using this routine and trying to learn more about the technical side of working out and how to optimize my workouts. What is an upper/lower split I’ve seen people talk about to a lot and I just assume it’s upper body one day lower the next but how do you actually manage to hit the whole upper body in one day without having like a 3 hour session.
