I did it for a year and it was extremely fun. It gave me the opportunity to become one with my feminity and sensuality, while losing weight and getting fit. When I finally built enough strength to flip upside and nearly fell on my head, I knew it was time to stop.
Unfortunately, through the exercise, I badly hurt my rotator cuff and killed my knees during the other exercises they offered. It wasn't a bad club, but I didn't do the exercises correctly, I guess.
