3 D is a friendly and clean place. They have great personal trainers, good equipment and convenient hours. My son needed to exercise desperately but hated any form of exercise before he went to 3D. John worked with him to set realistic goals and find ways to achieve them. Seeing benefits of exercise didn’t happen overnight, but John was patient and flexible in finding what worked for my son. This was a few years ago. Now my son goes to the gym regularly and voluntarily ;-) I know John is great at other stuff, like body building and weight loss programs, but I think his approach to teens is unique, so I thought is was worth writing about.
