Spinning Class

So I started spinning classes about 2 months ago. I thought I'd NEVER make it through one and now I go about 2 nights a week for 45 mins and man do I sweat!!! I love them because of that and I hate them because of it. I went tonight and he really kicked our asses. But...that's ok, that's what a GROUP EXERCISE CLASS is for, right? I haven't noticed any weight loss because of it, but I've gotten a lot toner from it. Which is better than nothing. I just like the way I feel when I actually accomplish a class.
