Tennis training device |
摘要 |
In a tennis training device there is a curved track whose curvature corresponds to the correct path that a tennis racquet should travel during a proper serve. The track has a channel along its length. The channel is sized and configured to receive a coupling which is attached to the head of a tennis racquet. The coupling travels along the track and allows the head of the tennis racquet to rotate relative to the track. The tennis racquet coupling preferably is a clip configured for releasable attachment to a head of a tennis racquet and a connector having an elongated body and a head attached to the body. |
