Abstract: The present invention is directed to a bowling aid which is secured to the hand of a bowler, encompassing the palm portion, wrist portion and the back of the hand. The palm and wrist portion of the bowling aid have aligned elongated rigid plate members that permit bending at a point that is close to their juncture. The back of the hand and the wrist portion of the bowling aid also have aligned elongated rigid plate members that permit bending at a point that is close to their juncture. Adjusting means are disposed in the palm portion, wrist and back of the hand portions of the aid to bend the bowler's hand in preselected desired angles and lock the position so selected.
