Ergonomic handle design: The resilience material combined with a contoured handle provides a comfortable, warmpalm fit. This design supports smooth, uninterrupted motions during water routines. Safe handling support: A double hand grip float board and double floating hand rings with antislip design ensure secure handling. This helps promote muscle memory for proper swimming postures and reduces the chance of slipping in water during use. Suitable for all ages: Engineered to offer stable buoyancy support, these discs help users master floating techniques and align with progressive training goals. They are effective for improving swimming power across multiple age groups. Enhanced training tool: By isolating movements, the discs help develop stronger legs and refine swimming techniques, maximizing the benefits of waterbased workouts. Use scenarios Beginner buoyancy practice: Use the dual hand grips and rings to learn body position, balance, and basic floating in a shallow pool. Leg strength and kicking drills: Employ the discs to isolate leg movements during water workouts, helping to build leg strength and improve kicking technique. Progressive training for all ages: Start with buoyancysupported floating and gradually increase difficulty to enhance overall swimming power for both kids and adults.
