“Until I met Bill, I thought I knew a lot about training. I’ve been working out with trainers my entire life, and had no idea I was wasting so much time, and energy. Now, instead of just trying to make my muscles big with weights, I’m giving my body the 6 things it needs to stay as young as possible, for as long as possible.”
