“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 | NYYankees

"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."

Dr. Joel Seedman on Calibrex
Dr. Joel Seedman | PhD Kinesiology

“When training alone, is difficult to see your own shortfall or imbalances. This device is just the thing I’ve been looking for to push myself that much further”

Arthur Torrens | University NH Head Coach


As high performers, our early community and the Calibrex team are devoted to challenging what used to be extremely expensive and inaccessible technology and bringing it to the hands of athletes, everywhere - unlocking access to specific key metrics to assess and optimize training while making confident and informed decisions.

Designing and upgrading the Calibrex systems has always one thing in mind: athletes' progress.

It's not just in the technology, it's in the people that use it.
