Material and durability Made from lightweight EVA material, this pull buoy is soft and comfortable, quickdrying, and designed for longlasting use in regular swim training. Performance and function Upper body strength training aid: Keeps your legs buoyant while you focus on arm strokes, helping to elevate your swimming performance without compromising body position. Design for effectiveness: features an eightfigure shape and a standard size (25 x 11 x 14 cm) to provide reliable buoyancy and a comfortable grip during drills. Stroke improvement and technique Helps refine stroke mechanics by promoting proper shoulder and arm movements, strengthens the back, improves breathing control, and supports more efficient, smoother swimming. Use scenarios Scenario 1: During main sets, isolate arm work to build upperbody strength and improve stroke power without relying on leg kicking. Scenario 2: Drillfocused sessions to emphasize shoulder rotation, arm path, and buoyancy control while keeping the legs buoyant. Scenario 3: Technique practice for beginners or intermediate swimmers to develop buoyancy awareness and refine stroke coordination in pool training. Specifications Material: EVA Size: 25 cm x 11 cm x 14 cm Shape: Eightfigure design Use: Pool swimming training aid for upperbody emphasis and stroke improvement Care Rinse after use and allow to air dry to maintain material integrity and quickdrying properties.
