20-40 min cardio (eliptical/treadmill/stair <-- either or)
followed by about 1.5hours of weight lifting. i have four routines:
chest and tricepts
back and bicepts
legs
abs/lower torso & shoulders

gained 4lbs and my friends said i look bigger. i was a little on the slim side (not that im the hulk now but...)

plus i wanna work in some pilates/yoga like what one of the other posters mentioned (yo, that pilates stuff aint easy!)

edit: done 4-5 days a week
