The BOSU® Surge® 40 is a cutting-edge training device built to improve overall health, fitness, and performance. Train better with the Surge® 40. Strategically placed angles allow the chambered water to crash and shift, allowing your muscles and core to react and engage on a whole new level. This provides a unique challenge to the joints and stabilizing muscles by forcing the body to resist and control the unpredictable nature of the shifting water. The Surge® 40's weight is fully adjustable and depends on how much water you add or remove; when fully filled the Surge® 40 weighs 40lbs. The 3 different grip options give the Surge® 40 the versatility demanded in today's performance training. From farmer's carries to overhead lunges the Surge® 40 will help you achieve your fitness goals by training your body to react to real-life movements as opposed to static movements. The advanced core training with the Surge® 40 offers over 50 innovative movement patterns that stimulate top-down instability the way it happens in life.
