Ive been lifting for a year and a 1/2 now. I do everything in 3 sets of 8 or more. Ive been thinking of breaking my routine up a bit though. Right now i do my chest and triceps along w/ my abs one day. The next day i will do my legs calves and my lower back. The third day i do my back, sholders, biceps, and forearms. When i get all of them done i start over. I was thinking about doing a cycle of heavy weight, 4 sets of 4 everyother time i do that body part. Say i do bench press monday using a heavy weight that i get a good burn from in 4 sets of 4 reps, then that thursday i do my normal 3 sets of 10. Whould this be wise, i figure i need to change something every here and there.
