This is my third week at Curves. Although I had a first initial bad experience (re: scheduling my first appointment to learn the machines), I really enjoy it. Everyone is very nice, it is all women, and it is a good work out. How much of a work out you get depends on how much resistance you use with each machine and whether you walk or jog on the pads. I also enjoy being on each machine for no more than 30 seconds and the fact that I don't have to wait around for someone to get off of a machine because there are only a select few. I give it two thumbs up.
