A golf training device is provided that includes a cord (flexible member) and a connecting device attached to one end of the cord to connect to a golf club, to a golfer's hand and/or to a golfer's finger. A housing may house the cord when the cord is in a retracted state, and the housing may allow the cord to extend therefrom based on movement of the golf club. The housing may include a mechanism to store information related to a specific amount of the cord extended from the housing, and an identifying device (or signaling device) to identify when the golf club is in a desired position based on the stored information.
