Sometimes your body just needs to rest. I work out daily for an hour, and take a spinning class on Saturday, walk 3 miles on Sunday, by Monday, my body has had enough! I usually take Mondays off and come home after work and just REST. By Tuesday I'm up and running, feel great and can just continue my workouts.

You are working out a lot, make sure you're getting a little more carbs/calories to compensate, you are doing great!

The body does need to regenerate, and there is no harm in taking one day off.
