摘要 <p>Golf club swing training apparatus includes a circular trackway (1) used with a modified golf club (2). The trackway (1) is defined by first and second planar surfaces (28, 8) which are spaced apart from each other a predetermined distance (17) so that the modified golf club (2) may be swung therebetween. The modified golf club (2) includes a weighted element (9) which slides on the first planar surface (28) when the club (2) is swung in the trackway (1). The weighted element (9) is in the shape of a disc having an aperture through the diameter thereof to receive the shaft of the club (2). The weighted element (9) is secured generally midway of the length of the club (2) by coil springs (10, 11) which encircle the club shaft and bear against diametrically opposite sides of the weighted element (9). Washers (19, 20) are affixed to upper and lower portions of the club shaft to retain the springs (10, 11) and weighted element (9) on the club (2).</p>
