Calling it a day...

I know when I've had enough. I swam for 1.5 hours today, there was 30 minutes remaining in swim practice and I called it a day. I had nothing left to give. I did my best while I was training, but my legs were absolutely useless and I needed more than the 10 seconds of rest between swims that I was getting. I have a chance to practice on Saturday but I've decided to take the entire weekend off swimming and give my elbow (and the rest of me) a rest.

I'm going to see how I feel later and decide whether to also take time off the P90X program this weekend. For now I need some much needed rest.
