I used to go to Ladies Workout Express. I enjoyed the workout, and did find I lost weight and got in better shape. It does get boring doing the same workout every time, even though they vary the machine order.
2 annoying things I found about it was:
1. the owner is a man, and I felt uncomfortable with all the ladies working out with the one man there
2. He is very pushy about wanting you to refer other people to the gym. He doesn't stop asking about it, and that really turned me off.
