The Arena Wonder Woman Heroes Kickboard looks super cool in an allover print and is a great swim training aid, enabling you to work on your lower body and improve your kick technique. FEATURES Dimensions: Length – 55cm Width – 28cm Depth – 5cm Improve balance and body position in the water: Rest your arms on the board and press your armpits down to bring your hips up in the water – if you just hold the kickboard your head will be up, which makes your hips lower in the water creating drag. You should kick from your hips for a nice big powerful kick. Ankles should stay below the surface to create more leverage and forward motion. Practice your kick stroke: Using a kickboard isolates your legs so that you can concentrate on your technique as you are not having to think about your arms. Some swimmers rely too much on their arms and drag their legs through the water. This will make you swim slowly and tire you out quickly. Improve leg strength: using a kickboard gives your legs an isolated work out and will build up lower body strength and endurance.
