I have tried several times in the past to work quads and hams on different days...the problem that i run into is that on both days i feel it in my glutes (when i hit hams, usually 3 days after quads, my ass is sometimes still sore)...i would like to try it again ---hitting quads on saturdays and hams on tuesdays....my quad workout will consist of hacks, front squats, and extensions...my ham workout will consist of stiff leggeds and various leg curls...any thoughts on how to avoid the "overtraining the ass" problem or other techniques for splitting quads and hams?
