Orange theory is the best workout I have ever experienced with visible results in six weeks! I have tried everything from Barr to yoga to Pilates to boxing to step classes. Orange theory keeps you motivated and working hard the entire time . The added heart rate monitor keeps you working to achieve your personal best ! It's fascinating to see as you get more conditioned that it becomes more difficult to Achieve your minimum splat points! I've had to increase my paces three times so far and weights are up seven pounds! ! Highly recommend this workout!
