Core Performance Book

The revolutionary book by Athletes' Performance President and Founder Mark Verstegen.  Released by Rodale Press in January 2004, Core Performance shows you how to use your core to transform your body and your life, turn back the clock, speed up your metabolism, trim your waistline, build muscle, and gain boundless energy.  More than a workout routine, Mark's 12-week,
comprehensive program reveals the athlete that has always been inside of you.

The Core Program shows you how to develop balanced fitness - strength, muscle mass, flexibility, power, and endurance - without overemphasizing or shortchanging any component.  It shows you how to recover from workouts so you get leaner and stronger when everyone else is just getting tired. And it shows you how to eat the right foods to get the body you want and the energy to have more fun with it.

These fitness principles, and the physical and emotional benefits, are
within reach of everyone - for an investment of less than one hour a day. Core Performance will show you how.

Core Performance Essentials Book

Core Performance Essentials boils down fitness essentials into a quick, easy-to-follow routine that requires minimal equipment and can be done in a hotel room, family room--even an office. It offers the benefits of yoga — with exercises designed to improve flexibility, joint stability, and balance — yet it also demonstrates easy, necessary strength moves using just body weight.


Featuring nutrition and lifestyle tips, this book will help readers have more energy and more time to thrive in their different roles all day, every day. This accessible exercise and diet program — perfect for those who haven't exercised in years as well as for anyone who wants a more streamlined workout — takes the same principles Verstegen uses to train elite athletes to thrive in sports, to help readers succeed in what he calls "the game of life."
