Hi, im 15 yrs old, 156 lbs, 5 ft 11. anyways, ive been on a 3-4 day total body workout from july to november-ish. ever since november, ive been doing a 4 day training split program, yet ive been having a bit of trouble geting to the gym 4 days a week. Is it possible to still see the same results by doing a 3-day training split program? And if so, what muscles should i focus on working out together during the same workout day? so far ive been doing chest-legs on one day, and biceps, triceps, shoulders/neck, and back the other day. any suggestions/advice greatly appreciated.
