Golf club training apparatus includes a switch in an electrical circuit in a golf club handle, and the switch is activated in response to improper grip pressure during the golf club swing. The switch is connected to a motor in the shaft. The output shaft of the motor includes an eccentric weight which, when the motor is turned on, sets up vibrations in the club shaft and alerts the golfer of the improper pressure occurring while the user is swinging the golf club.
