Designed by a chiropractor and consulted on by professional athletes, The BOSU Helm allows you to train your upper body for strength, stability, and endurance, while simultaneously working on your core. The BOSU Helm offers more dynamic properties to the general static plank position. The Bosu Helm can be used on the ground for standard pushup and plank support, and The BOSU Helm was engineered to sit perfectly on top of any full-size BOSU Balance Trainer or Swiss stability training ball (unstable surface), allowing the user a broad range of exercises. The BOSU Helm adds dynamics of strength, stability, and endurance training to your traditional core workouts, while focusing on abs, arms, shoulders, and upper/lower back all with one device.
