The Chelsea Football Club fitness trainer and coach, a former Olympic 200-metres finalist, describes the methods he uses to help players to build up stamina, to prevent injuries and to improve agility as well as strength and endurance. With guidelines on diet, circuit-training and weight-training schedules, warm-ups and pre-season work-outs, Mafe's all-round approach to football fitness is intended for players of all levels, including schoolboys, and for other men who simply want to get fit in the way that footballers do.
