A training device for competitive swimmers which can be adjustably mounted on a swimmer's body part and, in operational use, provides predetermined resistances of varying degrees to the swimmer's normal movements, causing him to exert greater effort, the resistances being generated by weights selectively and removably mounted within the device. Exploitation is made of the muscle as a sensory organ in generating a heightened awareness of muscle or tendon or joint movement.
