I've been training with Mack for 2 1/2 years and it is impossible to truly explain what I have learned about my mind and my body. I'm in the best shape of my life at 64. I have a six pack and I don't mean beer. I never get sick and I have a positive attitude. I had 3 surgeries in 18 mos and Mack rehabbed all of them. I may need a hip replacement in the near future and Mack will rehab that as well. He rehabbed Bo Jackson's hip replacement when Bo was told that he would never play baseball again. What did he do? A home run in his first at bat back in MLB. This is why I train with Mack Newton. Men, women, children and professional athletes train together (I do get a kick out of seeing pro athletes huffing and puffing with the regular folk). Come and join us. It'll be the best thing you can do for yourself.
