A comprehensive training program is necessary to enable your body to adapt and withstand multiple stimuli in order for it to perform at its peak level. Thus, runners should perform weight training exercises (i.e., overhead dumbbell presses, squats, lunges, leg extensions, etc.) to strengthen upper body and core muscles and to reduce injury risk. Weight lifters should run, bike and/or swim to increase their endurance and cardiorespiratory capacity. Cyclists should perform weightlifting exercises to maintain bone mass. All active people should perform stretching exercises to increase joint, muscle and tendon flexibility. Yoga can benefit any active person. No one particular exercise should predominate your regime. Instead, complimentary exercises are necessary in order to ensure moderation and balance.
