A method and device for golf swing training is disclosed wherein a double pendulum
model swing is replicated by defining a point on a golfer's chest about which a
golfer's swing rotates and extending therefrom a inelastic flexible strap for attachment
to the grip of a golf club. The inelastic flexible strap encourages the golfer
to fully extend his arms throughout the golf swing to maintain a proper swing radius
without inhibiting the movement of the golfer's wrists; therefore, allowing the
golfer to experience the ideal golf swing.
