Okay now that I know what it is it sounds like something I would like. Is this something a gym offers??

I went to a spinning class at Bally's one time and wow, it was SOMETHING! My behind did hurt but I def could tell it was working out my whole body. I was breathless!!! I don't go to Bally's anymore but when I get a chance, I think I may go back to somewhere closer to my house so it's easier for me to go. =)
