I get up at around 4:45 and work out for about 90 minutes, so I try to get to bed by 8:30 or 9:00. That doesn't always work out. Like last night, I was really tired but couldn't fall asleep until after 11. I still got up to work out. I woke up before my alarm went off, so I figured I was ready to wake up. I always feel great when I work out in the mornings, no matter how much sleep I've had. It's the afternoons that can kill me when I haven't had enough sleep. I am exhausted mid-day at work! Ugh! It really starts to catch up by the end of the week.
I have tried working out in the afternoons, but I am so much better off doing it in the morning. I also like to get it done in the morning so that if I am feeling good that afternoon, I can do another workout. I do that quite a bit and enjoy it.
