I use to workout every mourning, i'd wake up, take a quick shower, do some light streching, then off to the gym. I found i couldn't get a good pump from mourning workouts compaired to after work or later at night, but that was just me. I haven't done a mourning workout in awhile, i just find it better later at night.
1 good thing about mourning workouts were there wern't much ppl in the gym so i didn't have to wait or nothing, could get in there and get it all done without waiting or standing around..lol
