One giant rep for mankind.

A new dimension in strength

Optimize your workouts with the power of velocity-based training.

Automatic tracking

Automatic workout tracking

You lift, we track. RepOne is smart enough to count sets and reps automatically, recording dozens of datapoints about each.

3D motion sensing

Full 3D motion sensing

RepOne’s inductive sensor monitors motion in full 3d space, so you can track barpath, jump trajectory, and dozens of other movements.

Accuracy at all angles

Accuracy at any angle

RepOne’s tether is vastly more accurate than wearables or camera systems, and it maintains accuracy even when used at an angle.

Easy setup

Easy magnetic setup

Set up in 5 seconds. RepOne’s magnetic base clamps securely to a plate or rack, and the tether attaches to the object you're tracking via strap or roller magnet.

A month of battery

A month of battery

You read that right: RepOne can run for a week continuously, or up to a month if turned off between sessions--so you don’t have to charge it every time you use it.
