SPEEDO Kick Board Training Aids, Red, 1V3 Kickboard  (Red)

"Nail your kick technique and build leg strength. Ideal for technique sessions, the Kickboard puts the focus on your lower body, providing buoyancy so you can focus on perfecting the kick phase of your stroke. Without your arms for assistance, the lower body has to work harder to propel you through the water, which helps build leg strength and muscular endurance. Contoured for comfort, the kickboard includes grip holes for a comfy swim experience."
