I hurt my knees coming out of high school. 7 months later I was at my all time high of 310 pounds. After 5 months of training with Reggie and his staff my strength, endurance, sky rocketed with improvement. My weight is at 270 pounds . As for my knees I now have little to no pain. Science of Fitness is a daily routine for me now. It has helped me in many ways. Trainers interactions are great and so is the knowledge they give you.
