ABSTRACT:
A training aid primarily adapted to teach a tennis player proper form includes a hood, a headband, and an indicator for indicating when the user's head is tilted downwardly. The hood restricts peripheral vision and requires concentration on the ball. The indicator and hood may move relative to each other so that the indicator moves into the user's field of vision upon tilting of the hood.
