500 pound legs!

Today I used a bike machine at the gym. It wasn't the stationary bike, but the one you sit in like a chair and your legs are out in front of you. I don't know what that is called.
Anyway, I went 13.26 miles in 46 minutes on this thing! I was surprised I didn't burn out before that. I didn't really break a sweat or feel tired. I stopped because it was time to come home and fix dinner. The really funny part was when I got off the bike thingy. My lower and upper body felt like they were two separate entities. :) My legs were working but it was as if they weren't actually connected to my body. I almost laughed out loud in the middle of the gym. (which would have been seriously strange looking since I didn't have my headphones on anymore)
THEN...I went out to my truck and attempted to get into it. I say attempted because when I went to lift my leg up inside the cab, it didn't even clear the seat! It was hysterical. This time I did laugh out loud at myself. Luckily with a little upper body help I made it into the truck and headed home.
