ABSTRACT:
A golf swing training and exercising device comprises a vertical tubular member having a telescopic complementary tubular member for adjusting the height of the device, a tubular swing arm having another tubular member and a complementary member insertable therein to adjust the length of a swing arm, electrical signaling apparatus comprising a plurality of spaced switches which are in closed position when in contact with a cam housed on the swing arm. Certain signals are actuated by forward and backward movement of a grip, and other signals are actuated by rotary movement of the grip. Some signals indicate when a proper address, swing and follow through are made. A certain different set of signals indicate when a "fat" or "light" hit is made during a swing. The device, optionally, has a head restraining device which has an electrical switch that is adjustable for an allowable degree of head movement before it is closed to activate a signal indicating excessive head movement. The training and exercising device can be used with or without a golf club and with or without a golf ball or a practice substitute for a golf ball. A variable tension can be applied on a braking system to exercise and improve the strength of muscles employed during the swing. The device may also include a weight shift signal element wherein electrical switches are operated upon predetermined and timely weight shift from one foot to the other.
