Nice thread.
My routine is 3 days as well, Monday Wednesday and Friday. I do my biceps, back, pecs, obliques, and forearms on Monday and Friday, and my lower body on Tuesday. I also do abs nearly every day (body by jake, tae bo abs, "the firm" abs exercise. I do very little cardio, however I do run on a treadmill Tuesdays and Thursdays.
I am also on the "abs diet" (
www.absdiet.com) so my health habits of about the last month have been pretty decent. Ton of protein and low fat food = big muscles.
