A groundbreaking workout and diet plan that replenishes a man's testosterone levels, rebuilds his body, and remakes his life. Testosterone is the most crucial hormone in the male body--and every man's T levels begin a slow, steady decline as he ages. The result? Loss of strength and muscle mass. Poor sugar metabolism. Increased body fat, especially around the waist. Loss of T also affects red blood cell production, vitality, bone density, mental acuity, and sex drive. In short: It slowly chops a man down.
