Right now I'm doing full body 3 days a week. I usually switch up the order of body parts each workout as well as cycle a handful of main compound movements I prefer for their sport application. It usually follows along with your idea of, "focus on the legs one day, starting with squats, perhaps a bit lower in the reps followed by chest, perhaps a bit lower in the weight. Focus on chest the other day, fewer reps, followed by squat with more reps." It seems to work pretty well right now, but I wanted to make sure it was a sound concept.
I realize that squats alone will not make the chest grow, but I wanted t see if by doing the squat first, (as it is a bigger movement than the bench) would it create a more growth oriented state in my body for that workout? As opposed to starting it off with the bench which had a higher total set/rep volume than the bigger squat.
Thanks again guys.
