warm bed or the health club?

It was so hard to get up today and go to the club. Lately I just want to stay in bed and skip the club. I used to look forward to exercising, now I wish I could get fit just laying in bed. But since I can't, I got up and hit the club. I tried to keep my mets around 9 and I was pooped after 20 minutes. I kept going for another 20 minutes but didn't worry about the mets for the rest of my workout. I also managed to do some weights. I really admire the women who are training for triathalons. I read the blog of Heather and wish I had her determination and drive. I don't think I would want to do a triathalon, but I would love to have the energy and drive to train for one.
Maybe some day.
