Trainer-backed arm training aid for children that improves arm movement, core stability and swimming technique. Key benefits — why you need it Optimizes arm movement: Built on coach knowledge to guide correct arm paths and reduce inefficient motions during practice. Improves core and leg strength: Tailored buoyancy supports body balance and encourages stronger kicks for both freestyle (front crawl) and breaststroke. Easier, more controlled learning: A guided hand position reduces flailing and helps children repeat controlled strokes confidently, speeding skill acquisition. Durable, long-lasting training tool: Made from high-elastic EVA that maintains flexibility and shape, resists tearing, and stands up to intensive use. What makes it stand out Trainer-informed design: Hole pattern and overall shape were developed to direct the hands into an optimal position for effective stroke mechanics. Technique-focused buoyancy: Provides specific lift to promote proper body alignment and leg engagement for crawl and breaststroke practice. Material performance: High-elastic EVA offers a balance of bendability and form stability so the aid keeps its shape session after session. Function and compatibility Purpose: Arm training aid for children learning or improving freestyle and breaststroke technique. Use with: Swim lessons, coach-led training, and at-home pool practice—compatible with standard pools and swim-school environments. Performance: Guides hand placement, supports trunk stability in the water, and provides controlled buoyancy to reinforce correct kicking and body position. Practical use scenarios Swim lessons with an instructor: Use during guided drills to reinforce correct arm entry and pull while the coach provides feedback and progressive correction. Independent practice at home or community pool: Allows children to repeat controlled strokes safely, building muscle memory for consistent technique improvements. Skill consolidation between sessions: Ideal for short practice routines to maintain balance, kicking strength, and arm sequencing between formal lessons. Material and care Material: High-elastic EVA for optimal flexibility, shape retention and tear resistance. Durability: Designed to withstand frequent, intensive use during children's swim training. Simple, practical results Helps children develop reliable stroke mechanics and stable body position. Supports steady progress in swimming skills without complex setup or adjustments. Trainer-informed features ensure exercises practiced with the aid transfer to unaided swimming.
