发明名称 Baseball hitting aid
摘要 A hitting aid includes a waist belt that encircles a user's waist; the waist belt is attached using hook and loop fasteners, a buckle, or other. An ankle strap encircles the user's ankle; the ankle strap is attached in a similar manner. A stirrup is attached to the ankle strap and is arranged so that the user may insert his or her foot into the stirrup. An elastic connecting strap extends from the ankle strap to the waist strap, and is adjustable so that the distance between the waist strap and the ankle strap may be lengthened or shortened. When worn by a user, the hitting aid discourages the leg onto which the hitting aid is attached from being fully extended.
