- Practical training aid: The U-shaped design with multiple grip positions enables focused coordination training and helps refine essential swimming skills during practice sessions. - Anti-slip system: A specialized anti-slip texture combined with anatomical grip edges and skin-friendly material provides a secure grip and smooth training progression while swimming. - Adaptive design: Stable buoyancy during training transitions. The size-optimized form supports a wide range of swimmer preferences and techniques. - Visible practicality: High-contrast surface design clearly differentiates the board from the water, supporting focused training by reducing search time in the pool area. Use scenarios - Scenario 1: Beginners use the board to practice coordination and refine basic swimming skills during drill sets, focusing on grip, body position, and stroke timing. - Scenario 2: Intermediate swimmers switch between drills or techniques (for example different strokes or interval blocks) while maintaining stable buoyancy and secure grip for consistent performance. - Scenario 3: In pool environments where quick visual reference is important, the contrasting surface aids concentration and helps swimmers locate the board quickly between sets.
