Smooth SailingWe all know traditional workouts can be tough on the feet, knees, and joints. Try changing things up with low-impact aquatic exercise. You get the same benefits of aerobic cardio, with the added resistance and comfort of a refreshing pool of water. Plus, low impact exercise helps you avoid the aches and pressures of running on a treadmill or concrete. Whether getting in shape, burning calories to achieve weight loss goals or training for a healthy, physically fit swimming season, you're all set for smooth sailing.Why You'll Love ItOur comfortable flotation belt and adjustable buckle and strap provide balance and buoyancy for most body types.
