A training device mountable to an arm of an athlete for developing a proper arm swing. The training device includes a support body mountable to the arm of the athlete, a sensor assembly carried by the support body for detecting displacement of the arm in two directions of movement with one direction of movement being rotation about the longitudinal axis of the arm and the other direction of movement being bending of the arm. A signal actuator coupled to the sensor assembly produces a detectable signal when the sensor assembly detects displacement of the arm in at least one of the two directions of movement.
