Appropriate for everyone from elite athletes to kids to weekend warriors trying to stay in shape, the BOSU Sport Balance Trainer helps you strengthen and coordinate several major muscle groups, including the muscles you don't see. The BOSU targets your core muscles--the muscles around your abdominal and back area--while you perform a host of different workouts, from squats and bicep curls to lateral shoulder raises and hip extensions. As a result, you not only gain strength, trim, and tone, but also improve your balance and coordination along the way. In addition, BOSU training helps strengthen the mind, with thoughtful movement that requires the participant to not only be physically involved, but also "here and present" with the mind fully engaged. By combining physical and mental focus, BOSU training will boost your performance across a wide continuum of activities, including sports, recreation, and daily tasks.
