It may only be 30 minutes a day, but you really work your butt off!!!
I wish I didn't have to drive to town everyday to go to Curves or I would be signing up again. It's all women and they are all different sizes. I liked it because it's all in a circle, everyone can see everything, but it was fun. You can carry on conversations with everyone (if you're not too out of breath) and there were times we laughed so hard we darn near cried. Not laughing at us exercising, but from just funny conversations. I don't know if they are all like that, but the one in town is really fun.
