What it does Increases water resistance to strengthen muscles and improve stroke mechanics — ideal for beginners who need controlled, measurable resistance. Encourages a frog-like swimming motion, helping the swimmer catch water faster and generate more effective propulsion. Key benefits Builds strength and endurance through added resistance without changing basic technique. Improves the catch and pull phase so strokes become more efficient and faster. Easy to use: simple to put on and integrate into regular swim practice, offering maximum training efficiency for the user. Materials and performance Made from practical nylon material for reliable performance in the pool. Designed to provide consistent resistance and clear tactile feedback so swimmers can focus on technique. Typical uses Beginner swim lessons: accelerates learning by reinforcing proper kick and catch mechanics. Technique drills and lap training: add controlled resistance during focused practice to improve power and timing. Warm-up or conditioning sets: brief resistance intervals to build muscle memory and speed. Suitable for Swimmers learning or refining a frog-style kick and catch. Coaches and instructors who need a straightforward, easy-to-use resistance tool for group or individual sessions. Simple, practical, and focused on improving swim technique and efficiency while remaining easy to use and maintain.
