Abstract: A forearm/wrist positioner for maintaining a predetermined triangular relationship between the forearms and elbows of a trainee as the trainee swings a golf club from the address position, to the backswing, downswing, and follow-through positions and which includes at least one cuff member adapted to be mounted on one of the forearms and secured to one end of a spacer member the other end of which is pressed by the latter mentioned forearm against the other forearm for maintaining a predetermined distance between the elbows and forearms of the trainee as the latter swings a golf club from the address position through the follow-through position.

Abstract: Four embodiments of a sport swing harness (10, 10',10",10"') are disclosed. The sport swing harness (10,10',10",10"') is fabricated from a flexible, inelastic material. The harness (10,10',10",10"') includes at least one loop (16,16',16",16"') which extends around at least one shoulder of a trainee (14). A strap (18) of the same flexible inelastic material snaps over the back and under the second shoulder of the trainee (14). The end (22) of the strap (18) is held by the trainee (14) in his or her leading hand (24). The third alternative embodiment (10"') incorporates the harness (10'") into a sporting garment (32), such as a sweater, coat, vest or shirt.

Abstract: A stroke training device includes a guide member connected between the user's body and a stroking device which will focus the force of body rotation at a constant radius as the user's body moves between backstroke, stroking, and follow through positions; the guide member includes a reference surface located between the hand end of the stroking device and the user's body for defining a vertically extended reference plane located wholly between the hand end of the stroking device and the body within the constant radius of swing and moveable into a stroking or hitting plane including the object to be hit, which stroking and hitting plane is perpendicular to the line of contact with the object being hit for positioning the striking end of the stroking device within the stroking or hitting plane when the user's body is rotated into its stroking position.
