Hmmm
Let's see.
I change things up at least once a month. Most basic split is Push / Pull / Legs (usually thighs only). Everything from somehting similar to Big A split to a 3 day split, training 6 x a week. COuld be German VOlume training, Doggcrapp style training (like HST), Drop sets, HIT, other syles of Holistic training. My standard, if I had to pick one, would probably be training 3x / week, each BP 1x / week. But, I think the "magic" is in variety (along with hard training of course), not in the program (as long as its reasonably constructed to avoid overtraining.)
Recently, I've been doing the following, which gives me a differenty workout each time. Been Training 6 x / week, too, but shorter workouts (<45 min).
1x / week - thighs, focusing on quads
EOD - Calves, alternating high rep (15-20), short rest interval workouts with high load 6-10 reps, longer rest interval (HIT style). Just ~5 sets each workout.
Delts: 2 x / week each
--- 1 workout is us. 5 sets of side laterals, lighter weight (10-15 reps), short rest. Other is 5-6 sets HEAVY (HIT style): 2-3 OH press, 1-2 side lateral, 2 rear delt.
Chest is like like delts : 2 x / week. 1 light workout (1 exercise using a smith bench or incline) and a heavy workout - only 4 sets, 4 diff. exercises (HIT style).
Back is like chest and delts: but training only once every 5 days. (I do lots of SLDL's which hit lats pretty hard.)
Biceps, triceps: 1 - 2 times / week (HIT)
Trap, Forearms are trained w/ back: 3 sets each, HIT
Abs are EOD, light workout (100+ crunches), alternating w/ a heavy workout (2-3 sets of 10-15).
