I really like this place! I will be trying out the new office in Summerlin soon, I just haven't been able to sign up yet because the classes have been completely booked. I found out about this place through groupon. I got a a killer deal on 5 classes, which is really 6 since the first class is free. My first class was the mixed level and it was insane! The instructor was nice and the workout was exhausting! My girlfriend and I were sore as hell for 5 days afterwards. The level one class was a lot less strenuous but still a killer workout.
