Newton Fitness is for everyone. The Pro-Conditioning Class – led by Mack himself – plays host to professional athletes, busy executives looking to get back in shape, those recuperating from auto accident injuries, “weekend warrior” basketball amateurs and the occasional grandmother (among the toughest people you’ll ever see “in the house” to sweat beside you). If your dream is to feel better than you’ve ever felt, to be stronger, faster, more flexible, and to meet more of life’s challenges head on, then you’ve come to the right place. Between adherence to Mack’s classes and the “3-2 Eating Plan,” reaching your peak is only a matter of time.
