i work out sunday through thursday, sunday is chest (dumbells), monday is biceps, tuesday is triceps, wednesday back and shoulders, and thursday is chest (barbell) again if i feel recovered, if not i word on legs or just a mix of things. i have been doing this for about a month now, previously was every other day. i think i am growing more in my new routine, but feel much more fatigued than before. by the way i am not taking any supps. right now, but plan to very soon.
