The kBox targets many important aspects of developing golf players’ strength and is already used by several prominent golf trainers and their clients.

With flywheel training on the kBox, golf coaches get a tool for both general and sport-specific drills to target core, hip and upper body strength.


The kBox is a great training tool targeting many aspects of a golfer’s strength. Being able to load and train with high intensity without loading the spine and short-cutting the longer learning curve associated with many barbell exercises makes the kBox a very safe and effective training tool with a high and fast return on investment.

In golf, the kBox is used mainly to strengthen hip, leg, upper body and core. Single leg drills to emphasize core muscle training and bilateral exercises for higher force production work just as well. Can be used for personal training as well as in group settings.


The kBox offers intense training both in general and for sport-specific drills in a safe way. Monitoring and testing are added with the kMeter using metrics with high impact on performance. It’s portable and can be used outside of the gym on campus, trips and tournaments just as if you were back in your home gym.

The Harness reduces a lot of the torque and stress on the lower back which is a problem for tall athletes due to the long moment arms.

A study at the Par4Success Golf Performance Center found a 73% club speed gain following just 6 weeks of eccentric flywheel training. Learn more and download the full study here.


Existing clients in professional golf include Director of Performance Robbie Cannon of Cannon Performance, Director of Performance Ben Shear or Athletic Edge, Director of Training Joe Yoon of Baltusrol Golf Club and Founder and Licensed Physical Therapist Christopher Finn of Par4Success.
