These swimming hand paddles combine a flexible TPR body with a rigid PP paddle and adjustable PP strap to deliver comfort, durability, and measurable training benefits. Key benefits Boost propulsion and speed: The PP paddle increases water surface area to help generate more power during each stroke, which can help improve overall swimming speed. Build upper-body strength and technique: Using the paddles emphasizes the catch and pull phases of your stroke, helping to develop shoulder and back muscles and improve stroke efficiency. Comfortable, low-fatigue design: The TPR flexible body conforms to the hand for a comfortable fit and reduces pressure points, allowing longer training sessions with less hand fatigue. Secure, adjustable fit: The PP strap is adjustable to accommodate different hand sizes and keep the paddle stable during vigorous sets. Ergonomic shape: Contoured to follow the natural shape of the hand, the paddle promotes consistent hand placement and a more effective pull. Function and compatibility Materials: Flexible TPR body with PP paddle and strap for a balance of comfort and durability. Function: Training aid for improving power, stroke mechanics, and upper-body conditioning. Compatibility: Suitable for pool training, open-water swims, snorkeling, diving and general swim workouts; works for recreational swimmers and competitive athletes. Practical applications Swim training: Add to interval sets to focus on power and stroke technique during lap training. Triathlon or open-water practice: Use during long-distance or speed-focused sessions to build endurance and propulsion. Snorkeling/diving: Improve swim kicks and hand-assisted propulsion for less fatigue during surface swims or short dives. Care and use tips Start with short sets to adapt to the increased load on shoulders. Rinse with fresh water after use and store out of direct sunlight to preserve materials. Adjust the strap for a snug but comfortable fit that keeps the paddle aligned with your palm.
