Book excerpt: Strength and conditioning specialist Joe Kenn draws upon the three strength disciplines; weightlifting, powerlifiting, and body building, as well as training principles of traditional periodization and high-intensity training, to define the Tier System of athletic-based strength training. The tier system promotes training athletes on a rotation of movements (total body, upper body, lower body) rather than training body parts. The result is an integrated, whole-body strength training program with greater real-world and sport-appropriate applicability.The book explores an overview of the system, and provides annual plan development, training cycles, and daily and weekly plans. Ideal for coaches and trainers of football, basketball, track & field, wrestling, gymnastics and any sport requiring maximum and explosive strength.
