Coach-designed arm trainer that improves technique, builds core strength and lasts through regular children’s swim practice. Key benefits Improves arm movement and posture: Designed with coach input to guide correct arm positioning and movement patterns, helping young swimmers develop efficient strokes sooner. Builds core and leg strength: Even buoyancy promotes proper body balance and encourages use of core and leg muscles, supporting technique progression for freestyle (front crawl) and breaststroke. Better grip and control: Ergonomic 6-hole structure with targeted grip zones gives swimmers a secure, repeatable hand placement for more precise drills and faster skill retention. Durable, safe material: High-elasticity EVA compresses under pressure, returns to shape, and resists tearing — reliable performance for repeated use in children’s training. Features and performance Function: Stabilizes arm position, improves stroke mechanics, and creates uniform buoyancy to support balance and leg engagement during drills. Compatibility: Intended for children’s swim training and suitable for use in swim lessons, coach-led sessions, and independent practice in pools. Material: High-elastic EVA provides cushioning, shape recovery, and long-term tear resistance to withstand frequent use. Practical effect: Helps trainers and parents accelerate learning efficiency by making corrective feedback easier to apply and repeat. Typical use scenarios Swim lessons: Use during instructor-led technique drills to reinforce correct arm entry, pull patterns, and body alignment. Pool practice at home or club: Add to short repetition sets to isolate arm mechanics while maintaining balanced buoyancy for consistent practice. Stroke-specific training: Ideal for focused work on freestyle (front crawl) and breaststroke technique, where controlled arm position and steady body balance improve outcomes. What to expect Immediate, coach-aligned support for arm positioning and stroke control. Gradual strengthening of core and legs through repeated, balanced buoyancy-assisted practice. Long-lasting performance suitable for regular children’s swim training. Note: Product is made from high-elastic EVA and is designed for children’s swim training; follow instructor guidance for optimal use.
