Abstract: An instructional swing device for teaching the proper swing for baseball, golf or the like. The instructional swing device comprises a vest or harness arrangement which positions an adjustable, stretchable strap across the torso of the user from one shoulder to the opposite hip. Attached to the strap is an audible indicating mechanism, such as a buzzer, which is activated by proper movement of the user through stretching of the strap. In operation, the audible indicating mechanism identifies a proper swing during use to provide feedback to the user that the user is performing the desired hip movement in advance of the hands.
