If it wasn't for the Livingsocial deal, I would not have came to this place. I am glad I went; the workout is challenging, especially for your upper body and abdominals. It is normal to feel sore the next day, but it soreness hurts less the more you go. The instructors are also very nice and remember your face and name. The facility is also very clean and spacious.
The only thing I recommend they improve is that they demonstrate all the moves, especially for newcomers who don't know what a proper tuck is. I had to look to others to copy their movements because the instructor simply said to do something without showing how to do it. During my first visits, I had no idea what some of the moves were and sometimes had to crane my neck to see what everyone else was doing. At the very least, the instructors correct you when you still fail to do the movements correctly, and they're nice about it.
All-in-all, it's a good workout and I gained some muscle mass from only 10 classes.
