Strength has a speed.

Every lift tells a story. Velocity tells you what to do next.

The bar already knows.
We finally taught it to speak.

The signal // one rep
0.00M/S

Speed rises when you are fresh and falls when you fatigue. Velocity measures the change, then decides what comes next.

Your watch knows your body.
Velocity knows your lift.

Recovery

  • Sleep

  • Rep velocity

Recovery tells you how you arrived. Velocity tells you what to do now. Wear both. Velocity changes your next set.

Small enough to forget.
Precise enough to trust.

One module. Two mounts. Measured at the source.

MOUNT 01 // ON THE BAR

MOUNT 02 // BODY WORN
Bar mount

Direct load velocity, measured on the bar itself.

Body mount

Athlete and load moving together, for loaded work beyond the bar.

How it works

One signal.
One decision loop.

Measurement is necessary. Adaptation is the product. Every session runs the same closed loop.

01

Measure

Every rep captured at the source. Live bar speed the moment the weight moves.

02

Interpret

Velocity, fatigue, and your history read together. It recognizes deterioration as it starts.

03

Adapt

Load. Reps. Rest. Stop.

The next set changes to fit the athlete you are today. This is the product.

04

Learn

More individualized with every session.

Velocity loss crossed the limit. The set ends before quality deteriorates further. That is the difference between tracking and coaching.

Tested and evaluated by active special operations athletes since June 2026. The most demanding early users a strength product could ask for.

Patent pending

A patent is pending on the Velocity system. Sensor, engine, and decision loop filed as one invention.

Performance shouldn't depend on where you're standing.

One week I trained with world-class coaching. The next I was alone with a barbell in a plywood gym overseas. Same body. Same standard. Half the guidance.

So we built the coach that travels. It lives on the bar, and it never rotates home.

Before you ask.

How does Velocity measure a rep?
A motion sensor captures every rep automatically from its mount. On the bar, it measures the velocity of the load directly; on the body, it measures athlete and load moving together. Measured at the source, not inferred at the wrist.
What exercises does it support?
Barbell training is the core: squats, presses, pulls, and their variations. The body mount extends measurement to loaded movement beyond the bar.
Does it work without my phone?
Velocity pairs with the app for live coaching, so keep your phone within reach of the rack. The app is where the decisions land.
Can I run my own program?
The beta runs Velocity's own velocity-guided programs. Support for running your existing programming on top of Velocity measurement is in active development.
Can I wear it with my watch or recovery band?
Yes. They read your body; Velocity reads your lift. Many of our beta athletes wear both.
What does membership include?
Adaptive programming, live set guidance, performance history, your athlete model, and software updates, at $19.99 per month. It is required for sensor operation. Cancel anytime.
What will Velocity cost at launch?
$199.99 for the sensor, plus the $19.99 per month membership. The Founding 300 order at $149.99.
When will it ship?
Founding members are invited to order first, in order, when orders open. We publish build reports instead of promising dates we have not earned yet.
What is the return policy?
30 days from delivery, full refund on hardware and membership, no interrogation.
