Now in a revised and expanded second edition, Optimal Muscle Recovery is a valuable training guide-a must-have for serious endurance athletes or anyone looking to train harder and recover faster. Author Ed Burke is one of the country's leading exercise physiologists, having worked with professional athletes such as runner Frank Shorter and Tour de France champion Lance Armstrong.

His recovery program, called the R4 System, is nothing short of revolutionary and has been touted as "breakthrough" research by leaders in athletics. New material includes recovery for the masters and strength athlete; the importance of sleep and nutrition in recovery; and the latest on supplements and sports drinks to aid in replenishment.
