Yoga is a great place to start.
I see many athletic people brush aside yoga. It's too slow. Yoga can be an energizing and motivating addition to your fitness program, no matter how intense you like your workouts. A weekly yoga workout gives your body a rest from the beating of a traditional aerobic or weight training workout, while enhancing your strength, agility, balance, and concentration. Athletes in peak form turn to yoga to help them focus and gain an extra edge.
