How it works
How REP RUSH counts your reps
No wearables, no downloads, no setup. Open the page, allow your camera, and on-device AI does the counting while you lift.
Hit play, allow your camera
Everything runs in your browser. Your video is never uploaded or recorded — the AI reads the frames on your own machine.
Calibrate in one rep
REP RUSH watches a single rep to learn your range of motion, so half-reps and small twitches don't count.
Rush your reps
Clean reps fire combos, charge the Power Core, and light up the screen. Break your form and it won't count.
Made for real life
No gym? No time? No problem.
REP RUSH is built for the in-between moments — a quick win you can grab without changing clothes, booking a class, or leaving your desk.
On a work break
Five minutes between meetings? Flip it on, bang out a set, and get back to it. No commute, no changing, no setup.
No gym, no gear
Your room is the gym. Bodyweight squats or a pair of dumbbells — REP RUSH counts them either way.
Keep your streak alive
Every session feeds your streak and workout history. Small daily wins stack up fast — and they're weirdly addictive.
Why it's different
A rep counter that only counts real reps
Counts real reps, not wiggles
Form gates check that the right joint actually moved the right way — a forearm aimed at the camera won't fake a curl, and a half-squat won't score.
Private by design
On-device AI means your webcam video never leaves your machine. No server, no upload, no recording — ever.
No gear, no account
Just a browser and your webcam. No wearables, no app store, no signup. Weights are optional for curls and presses.
A workout that plays like an arcade
Combos, a Power Core, procedural music, and shader effects react to every rep — so a set feels like a high-score run, not a chore.
Exercises
Pick a move, count every rep
REP RUSH counts these today, with more on the way. Each exercise has a guide on how the AI tracks it and how to nail your form.
Privacy
Your camera stays on your machine
REP RUSH runs the pose AI entirely on-device with MediaPipe. There is no server to send video to, nothing is recorded, and nothing is stored. The only thing that ever leaves your browser is a screenshot — and only when you choose to save one.
