HOW TO DO A PROPER PUSH-UP

Setup  Get into a plank facing down, side-on to the camera, hands under your shoulders.

  1. Lower your chest toward the floor, elbows ~45° from your body.
  2. Keep a straight line from head to heels.
  3. Press back up to full arm extension.
Form cue: Chest to floor

How The Check Works

THREE STEPS TO A SCORED PUSH-UP

1

Prop your phone and get in frame

Phone at roughly torso height, set up side-on to the camera. A quick camera test checks lighting, distance, and angle before you start.

2

The camera locks a 17-point skeleton on you

GOODREPS measures your elbow angle (shoulder → elbow → wrist) on-device — no wearables. No equipment at all — just floor space and your phone propped side-on.

3

Move — and watch the form bar

The bar fills from ~155° toward ~70° at the bottom. Cut range short and it tells you; full ROM is what counts.

Under The Hood

WHAT THE CAMERA WATCHES

Fix These First

COMMON PUSH-UP MISTAKES

Sagging hips

The plank breaks before the arms do. Squeeze your glutes and brace your core so your body moves as one line from head to heels.

Flaring elbows out wide

Elbows at 90° from your torso grind your shoulders. Keep them about 45° from your body — closer to your ribs than your ears.

Half reps at the top or bottom

Not reaching the floor, or never locking out. GoodReps catches this automatically: partial range of motion doesn't bank a rep.

Craning your neck

Looking up bends the chain at the top link. Keep your gaze down and your neck neutral — the line runs head to heels.

Your Data

PRIVATE BY DESIGN

Rep counting runs entirely on your device — your camera feed is never uploaded.

Pose detection runs in your browser via TensorFlow.js. Camera frames are analyzed in real time and immediately discarded — nothing is recorded, nothing leaves your phone, and we never see them. Sign-in is optional; skip it and everything stays local.

FAQ

QUESTIONS, ANSWERED

Do I need any equipment to count push-ups?

No — push-ups are the purest bodyweight movement. All you need is floor space and a phone propped side-on at roughly torso height.

Does it work in a home gym or low light?

Run the built-in camera test first — it checks your lighting, distance, and angle with live green checks before you start. If a rep still slips through, manual counting is always one tap away.

Is my camera feed uploaded anywhere?

No. Pose detection runs entirely on your phone, in your browser. Frames are analyzed in real time and immediately discarded — nothing is recorded, nothing is uploaded.
