​The pull buoy is a flotation device placed between a swimmer's legs to support the lower body. It helps isolate arm movements, allowing swimmers to focus on improving upper body strength. It is a very effective way to finesse arm technique. Pull buoys should be used as a part of a training programme to the swimmer does not become reliant on the additional bouyancy. Pull bouys should always be used as a swimming aid not a buoyancy aid.
