Contestant Mark Sweeney, 43 , works for the railroad but at a desk most of the time. “I used to work out consistently and then I got lazy,” said Mark. “I knew I had to make a change so I joined the Body Transformation Challenge. With Rob and Trainer, Joe Freitas’ help I began to workout consistently five days a week combining cardio and weight training. I do the elliptical, the rowing machine and spinning.  I also made real lifestyle changes including my diet with Rob’s help. I eat a lot of the same foods but smaller quantities. I’ve lost 30 lbs. and I feel great. Joe and Rob provided the motivation and the proper methods to get and stay fit.”
