Wow, I am so not strong enough to do a spin class. As a matter of fact I realized what a wimp I really am today. 30 minutes on treadmill and then 15 minutes into the elliptical I get a cramp in my arch! OOOWWWW! However, I am as stubborn as I am ... well anyway. So I refuse to get off until I hit 30. However, when I hit thirty I came off of there very quickly and have been whining ever since! I tried the bike, nope, not with that soreness. *sigh*. Going back tomorrow!
I am so impressed that you will be doing spin class
, I wouldn't last 5 minutes.
