英英释义

Pull buoy

  • abstract: A pull buoy or leg float is a figure-eight shaped piece of closed-cell foam used in swim workouts. Swimmers place the buoy between the legs – between their thighs or their ankles – to provide support to the body without kicking the legs; this allows the swimmer to focus on training only their arms and developing both endurance and upper body strength.
