发明名称 Tennis training aid
摘要 A tennis training aid can be used to teach proper wrist and racket position for swings such as a forehand ground stroke, two-handed backhand stroke, or volley. A training aid includes a forearm attachment member that can be quickly and easily attached to a player's forearm. A wrist positioning member can be attached between the forearm attachment member and the player's racket to maintain proper wrist angle and racket position. A first wrist positioning member can be used for a forehand ground stroke or two-handed backhand stroke, while a second wrist positioning member can be used for volleys. The forearm attachment member can include a rotatable member, and the wrist positioning member can be slightly elastic, in order to allow the racket to move slightly with respect to the wrist, and to allow for slight wrist movement, in order to provide a natural feel for the player.
