The Sprint Board from Aqua Sphere is a swim training aid designed to isolate your legs to improve your kick technique, lower body strength and balance in the water. This dynamic shaped kickboard is comfortable to hold with hand holes and has a hydrodynamic, contoured shape for less drag and more speed so that you can sprint with it, practising your racing kick.
Very lightweight and buoyant . As a swimmer it worked effectively in training and could be classed as more versatile than the larger boards. The only downside is that the shape is annoying in a bag , especially with other kit. The board is thicker than most.
