With our classic pull buoy, you can focus more on your arm technique and exert yourself. The pull buoy is designed to isolate the upper body. It provides buoyancy between the legs, allowing you to refine your arm stroke and improve your movement technique. Without the strength of your legs, your arms and shoulders take on the load, enhancing the strength and endurance of your upper body while swimming. Use it to improve your body position for greater speed and efficiency.
