发明名称 Backswing release handle
摘要 An exerciser uses a handle and bracket combined with a resistance that opens the bracket away from the handle to facilitate wrist cocking in a backswing region of a simulated swing. As the handle moves downward and forward toward a hitting region of the swing, the bracket moves to a closed position requiring the exerciser's wrists to uncock against the resistance in approaching the hitting region.
