It's not like outside. It's on those exercise bikes...Which I'm not sure would be exactly the same, but I used to for like 2 weeks go 2 miles outside. Then I thought it got to hot so I just used the bike in my mom's bedroom. I hate biking too, but I figured I'd better start doing something...I feel better after I get done though. :]
Hmm, well my back still hurt. I'm not sure..it might be our floor. We had to do lots of sit ups for our physical fitness test and we had the mat things out...and my back didn't hurt....I don't know.
Which reminds me no more fitness tests ever again. They made us run a mile....let me say it was NOT fun. Biking...yah....running...HAH..yea right.
