Apparatus for use by one manipulating a device to be swung such as a golf club, bat or the like. A flexible cord is anchored at one end thereof and has the opposite end affixed to the device to be swung at a point displaced from the grip end thereof. A slide assembly engages the cord between the ends thereof to shorten and lengthen the amount of cord available between the slide assembly and the point of attachment to the swing device as the device is swung by the user. In one embodiment, the cord is threaded through a tubular member disposed to permit additional cord to be pulled therethrough as a swing is executed, while in an additional embodiment, a slider traverses a guide mechanism during the swing and thereby permits additional cord to be presented between the swing device and the slide. |
