It takes about 35 minutes to go three times around the circuit, and it really goes by fast. You definitely don't get bored. Then you do some cool-down stretching, and that's it. There are no showers, no pools,or anything fancy. The one I go to is set up in a small strip mall about a mile from my home.
What I like is that there are very, very few 20-year old hardbodies (love 'em, but they make me feel old and frumpy). Thare are some women who are really heavy, who are also on the Curves diet program. I haven't gotten into that yet (although I should lose 20 pounds), just don't have the motivation yet.
I do feel like I've toned up quite a bit though, the love handles seems to be tightening up, the back of the upper arm (bat wings) are starting to melt away.
I think all Curves for Women offer a free one-time trial run through the circuit, and I would definitely recommend giving it a try to see if you like it.
