Why Water Roar? Roaring works 84% of remussel mass. More than any other exercise, Roaring recruits all major muscle groups. From the tips of the fingers to the balls of the feet, all the muscles between these two points contribute to the rowing stroke. By maximizing the muscle mass, contributing to the exercise, the water roar provides the most benefit in the least amount of time. Roaring can burn more than 1000 calories per hour and compared to other aerobic exercise, it doesn't feel like you're working as hard. By spreading work over a wide range of muscles, Roaring consumes calories in more muscles, allowing more calories to be burned within the user's limits of fatigue. Other exercises recruit fewer muscles and require far higher intensities of exercise to burn the same number of calories. Roaring moves your joints through a full range of motion and does so with minimal impact and no body weight on the joints, making it one of the best exercises for joint pain sufferers. Roaring is suitable for everyone. Younger old, male or female, bigger, small, fit or unfit. So if you are looking for a fun, effective, efficient and low-impact way to get or stay fit, come into Matthew's today and try a water roar.
