Thanks, my friend is really into the spinning right now, a heart rate monitor sounds like the kind of thing she'd be interested in.

As for good weight vs bad weight I'm sure that if it was muscle weight she had gained she wouldn't be complaining. Her quote: "I
should be super huge by now, but instead, I am super HUGE (ie: not the good kind)". She's been doing weights a few times a week along with the spinning.

While I'm sure she hasn't balloned out in size, I think that she would like to get the most out of her exercizing. I think the heart rate monitor would be the best tool for her to optimize her spinning classes. When we get back to school in September I'll get her to go out and do some out doors riding, and when it gets too cold I'll go indoors and do spinning with her.

Thanks for the replys!
