Abstract: A golf swing training aid that is effective in aiding a golfer in acquiring a proper golf swing. The training apparatus includes a simple, non-encumbering support that can be removably connected to the upper body portion of the trainee. The support consists of an elongated, upper body-encircling strap and first and second spaced-apart shoulder strap assemblies that are connected to the upper body-encircling strap. An important feature of the training aid involves providing first and second specially designed, yieldably deformable underarm pads that are connected to the upper body-encircling strap by elongated connectors and are conveniently movable by the trainee from a hanging position when not in use to an underarm position training position.
