US Patent 7901304 Golf teaching device

The training device is made in two pieces that are mirror image of each other. In the first embodiment which is used to improve an individual's general swing the two pieces are laid together such that the two inclines form a valley. To use the device one steps on the inclines and places his feet approximately shoulder length apart in parallel with the valley. One then takes up a stance to swing. As he practices swinging the golf club he noticed how his body feels with the weight on the insides of his feet. By him standing on the inclines he will keep his feet, hips, shoulders in the proper position for a correct swing.
