is a figure-eight shaped piece of closed-cell foam used in swim workouts. Swimmers place the buoy between their thighs or their ankles to provide support to the body without kicking their legs; this allows the swimmer to focus on training only their arms and developing both endurance and upper body strength.
Using the pull buoy gives the arms a more focused workout by providing flotational support for hips and legs. Good body position and technique can be established and a bilateral breathing rhythm can be refined.
