Highly recommend this gym for women! There are no gross mirrors. There are lots of other women in the room. You will get an excellent workout (the trainers do not mess around), but you will also feel safe at the same time.

This is the best gym around! I've been going here weekly since they opened their doors. Best trainers and bootcamps, if you want a great workout come check them out.

Been training with Bobby for over 10 years and recently joined the power for golf program. I was surprised at how much swing speed I was able to gain in such a short amount of time, and how much control I still felt like I had over my swing!
