When you use the exercise tracker, our AI reads your pose keypoints — the joint positions on your body (shoulders, elbows, hips, knees, etc.) to count your reps accurately.

Your movement data helps us improve rep detection accuracy for everyone. Bodies move differently — the more variety we see, the smarter the model gets for all users. Your data makes Reps better for you and the whole community.

All data is aggregated and anonymized before being used in model training. It is never sold, never shared with third parties, and never used to personally identify you.
