I work out from about 8 to 10... with about 20 minutes dedicated to driving, 20 to some sprints which i do after i lift, and the other time allowed for resting and lifting. Btw, that is in the morning. I eat breakfast at like 7 o clock and have some coffee... but i am still a little out of it at this time. Though, because it is summer, I don't have time to do it later in the day. Err... well i do, but i'd rather be having fun with friends. I lifted at 11 today though, and, i didn't have an increase in energy. I'm more of a morning person than a night person; i get so tired around 10 o clock. If i stay up to 11 though, i become overtired and can stay up as late as i want.
