Cupp Golf

Cupp Golf is a golf instruction and equipment brand focused on helping players develop a more consistent swing and spend less time on unproductive practice. Founded by the Cupp brothers, whose golf backgrounds include instruction from Mike Austin and Joe Norwood, the company applies their professional engineering experience to its swing-training aid, The Radius.

The Radius is designed to help golfers feel and practice correct swing mechanics. It supports proper hand and wrist positioning, body coordination, and control of the clubhead through the impact area. According to Cupp Golf, the training aid helps address common swing issues, including wrist misalignment, cutting across the ball, shoulder movement, and a collapsing lead arm. Its adjustable design accommodates different arm lengths, clubs, shaft lies, body sizes, and heights. Made with durable materials and ergonomic principles, The Radius is intended for golfers at all skill levels, from beginners and casual players to amateurs and tour-level professionals.
