Cupp Golf™ was founded in 2019 by brothers Jared and Myles to carry on a golfing legacy. Jared and Myles, along with their brothers Owen and Austin, were raised with a lifelong passion for golf by their father, Charles. Charles sought out the very best in golf instruction and his sons were personally instructed by golf legends Mike Austin and Joe Norwood. Jared and Myles are now applying their many years of experience as professional engineers towards creating The Radius™ – a swing training aid based on well-proven golf theory.
Cupp Golf™ seeks to revolutionize golf instruction by bringing to the world, at last, a way to genuinely feel a correct golf swing. Cupp Golf™ wants to free golfers from spending countless hours of fruitless practice and to give golfers what they seek – more time to play the game and to play it well!

The Radius™ eliminates errors in the wrists and hands, including overcocking, overflexion, overextension, overpronation and oversupination.

The Radius™ trains precision hitting and coordination of the body. It eliminates the cut-across, the smothered hooks, the shoulder wobble, and the left-arm collapse.

The Radius™ teaches the muscles to control the clubhead for a powerful release through the impact area every single time. It keeps the clubface in perfect position throughout the swing by maintaining correct wrist alignment and constant radial arc.

The Radius™ is designed with tour-level professionals, amateurs, the casual weekend golfer and the absolute beginner in mind.

All components of Radius™ are engineered from highly durable materials using principles of ergonomics to create a comfortable, powerful, and easy-to-use swing training aid.

The Radius™ is adjustable to fit the length of the golfer’s arms, their clubs, and the lie of the shafts. The harness system is also adjustable to accommodate golfers of varying sizes and heights.
