Like us, humans, each Calibrex 1.0 is unique.

During this limited edition launch, all Calibrex 1.0s are handcrafted in-house (in New York City), and will have your initials on! 🚀

-> Share your feedback on the Calibrex 1.0, and work directly with the Calibrex Dev Team to develop and test new features.

-> Vote new features - Gain access to the private Calibrex Discord group, where you can chat and exchange ideas with other Calibrex users, and get the latest announcements.

-> VIP - We're huge on rewarding our early adopters, which means you'll be the first to get your hands on new hardware, exclusive merch early access and unique community discounts.

“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
