This place is amazing. Pure and simple. If you are looking for intense cardio, interval training, I highly recommend it. The exercises are hard, but extremely fun, and the classes are relatively short. About 40-ish minutes. They are basically built on riding a stationary bike for a minute, running to the floor and doing an exercise for another minute. Rinse and repeat.
You get a partner that is around your height so that the bike portion is easier and one rides while the other is on the floor doing an exercise. Classes are also all split up into teams. A, B, and C. Each group does a different exercise.
The trainers are extremely friendly and while the exercises are hard, they do a very good job at keeping you motivated to work through it. They are also very good at helping first timers. I recommend it. If you are interested, they also offer a free class before joining.
Good job guys and keep it up!
