"Velocity based training is a great method for determining each athletes readiness for a days workload and using metrics is the only way to track"

Brad Hyde | Athletic Trainer @ NY Yankees

"Amazing product. Velocity based training is made super simple with the use of the Calibrex system. It has allowed some of my athletes to take more ownership of their programs. They can follow their progress in real time."

"Being able to track your metrics when training particularly with foundational barbell movements is potentially an invaluable tool that previously has only been available in high-tech physiology labs."
