I came to the realization that if I did not do something to lose weight and get into better shape, I never will. I had just turned 55 years old and could not walk up the stairs at the train station without extreme pain in my right knee. Santiago has strengthened my knee to the point that not only can I walk up the stairs pain free but I can run up them. In addition, I have lost 35 pounds and my waist has been reduced by 6 inches. Even more astounding is that I can actually run again, which is something that I have not done in over 10 years. Though our workouts are tough, they are never boring. Santiago changes things up which keeps working out fresh. I feel 15 years younger and as strong as I can remember.
