What do you use this for?You can use the pullkick in two ways while swimming: as a pullbuoy and as a swimming board. It's more suitable for advanced or expert swimmers, as it offers moderate buoyancy as a board. Its dimensions are optimized so it doesn't slow down your swimming speed. Clamp the pullkick between your lower legs to work on your form. You can also use the pullbuoy with an elastic band to keep your legs still.
