I've worked out as late as 10 or 11 also, but that is extremely rare for me! I used to get up at 4:30 to drink some java, get myself woken up, and working out by 4:45 or 5:00 a.m. Those were not my funnest days and I'd crash and burn early afternoon. Now, I'm not working so it's been nice to get my workouts done before my hubby comes home from work but I don't have to do it early a.m. or late at night anymore.
