Tied on the Weekends

Hi Everyone,

I have an odd situation here. I typically work out 4 times a week during the week day and then take it easy on one weekday the weekends. I also stick to more low calorie foods on the week days, but try to stay within my calories on the weekend. The thing is that I can't seem to stay awake on the weekends. I'll sleep a good 9 hours and then still take a 2-3 hour nap on Saturday and Sunday. (On the weekdays I'll get about 7 hours of great sleep and feel fine, even on my day off). I'm not sure if I'm going to hard during the work outs or need to add some to my weekends to avoid sleeping at 5 pm!

Please help!

Thanks!
