Right now I train every day, 7 part split. Workouts are always under a half hour. Sometimes I train at work, sometimes at home. I never go to a gym anymore. Too many bozos, and ya gotta pay. Plus you gotta wear clothes. I hate that. And most gyms aren't 24 hours. My living room / gym is.

MO abs (15 minutes tops)
TU delts and traps with some tri-sets some times.
WE upper back
TH chest
FR thighs, glutes, lower back(sometimes this one goes slightly over the half hour)
SA forearms and calves
SU upper arms, supersetting.

If I go back to a more normal 3 part split, my sessions will probably be close to an hour. As it is now, it would suck to spend longer walking to the gym than being in the gym. I just like training alone, and I enjoy short sessions.
