BREX Founders Class 🔥

Big shoutout to for organizing an awesome private group session in Studio 2 with seven other San Francisco founders. Led by , this workout brought together a group of innovators for some strength, cardio, and a good time.

Running is booming right now — but how you move matters just as much as how far you go.

3D Gait Analysis uses motion-capture technology to assess your stride from every angle, measuring joint movement, symmetry, and efficiency in real time.

It’s the data you need to move better, reduce injury risk, and unlock more efficient performance — whether you’re just starting out or chasing a PR.

Every Gait Analysis comes with the opportunity to try multiple shoes, a full breakdown of results, and corrective exercises for any imbalances.
