A friend and I found JAB on Groupon. After our first kickboxing session we both looked at each other, and knew we had to cancel our other gym membership. This class really delivers a great workout, and the trainers totally make it enjoyable. The weekend bootcamps are our fav, as the workout touches on every part of the body. The trainers remember your name, and they really do a great job at helping you out with the exercise routines. I have done Lifetime Fitness (Gilbert), SNAP Fitness, Stick2ITFitness, StudioFit, and LA Fit. JAB hands down beats all of those competitors.
