I just checked the workouts in that thread, and I have one question...
How in the hell does anyone have that much extra time?? Seriously though, I work 8 hours...lucky to get even a decent amount of lunch (I eat a pudding, an apple, and carrot sticks most days for lunch) and then I get home, make a decent dinner, usually chicken every other day.
So most of my day is wasted driving to work, working, driving home, time to make dinner, clean up the mess, get a shower in, read before I go to sleep, then sleep for (if' I'm lucky) 7 hours. Then repeat.
