An adjustable arching arm attaches to a top portion of a golf club such that the adjustable arching arm is generally in alignment with a club face. The adjustable arching arm is adjustable in a generally vertical plane to accommodate chip shots and full swings. In a chipping mode, the adjustable arching arm is in a lower position and is intended to maintain contact with an inside of the left forearm (of a right handed golfer) through a chip shot thereby training the golfer to hold his (or her) hands in the correct position through a chip shot. In a full swing mode, the adjustable arching arm is adjusted to an upper position such that the adjustable arching arm is able to move from inside of the left forearm to outside of the left forearm during the swing to indicate good hand position.
