Why AI Fitness Rep Counter Works Here
17-point skeleton at 60fps
Tracks head, shoulders, elbows, wrists, hips, knees, and ankles in real time — enough resolution to actually see form, not just a rough silhouette.
Live joint-angle measurement
Reads elbow and knee bend in degrees in real time — useful for checking squat depth or a joint lockout without eyeballing it.
Multi-Person tracking
Tracks more than one person in frame at once, each with an independent skeleton — useful for a trainer-and-client setup or a small group session.
Gesture Labels
Calls out a handful of held poses ("Arms Up!", "T-Pose") automatically — a geometric check, not a trained classifier, so it looks for a clear held position.
Color by Side
Tints left- and right-side joints/bones differently so orientation and left/right symmetry are visible at a glance.
Works on webcam or recorded footage
Check form live during a set, or load a recorded workout clip and step through it frame by frame afterward.
Frequently Asked Questions
Does this count reps automatically?
It doesn't run a trained rep-counting classifier — it gives you live joint-angle numbers (e.g. knee/elbow bend in degrees) and a stable skeleton to watch, which is the raw signal a rep counter would use, but counting itself is currently a manual watch, not an automatic tally.
Does it work for any exercise?
Pose Estimation tracks the same 17 body landmarks regardless of the movement, so it works for squats, presses, lunges, or general movement analysis — anything where seeing joint position/angle live is useful.
Do I need a special camera or sensor?
No — any webcam or an uploaded video works. No depth sensor or wearable is required.
Can more than one person be tracked at once?
Yes — Multi-Person mode tracks each person in frame with their own independent skeleton.
Is my workout video uploaded anywhere?
No — everything runs locally in your browser. Nothing is ever sent to a server.
