Push-Up Form Check
Is your push-up actually good? Prop your phone up and find out — GoodReps watches your elbow angle (shoulder → elbow → wrist) live and scores every rep as you train your chest and triceps, with shoulders and core assisting. Free, in your browser, processed entirely on your device.
▶ Check My Form FreeHOW TO DO A PROPER PUSH-UP
Setup Get into a plank facing down, side-on to the camera, hands under your shoulders.
- Lower your chest toward the floor, elbows ~45° from your body.
- Keep a straight line from head to heels.
- Press back up to full arm extension.
This is the same instruction sheet you’ll find on the ⓘ panel inside the app — with an animated demo next to it.
THREE STEPS TO A SCORED PUSH-UP
Prop your phone and get in frame
Set your phone at roughly torso height and set up side-on to the camera. The built-in camera test confirms your lighting, distance, and angle with live green checks before you start.
The AI locks a 17-point skeleton on you
GoodReps measures your elbow angle (shoulder → elbow → wrist) in real time, entirely on your device. No wearables, no sensors. No equipment at all — just floor space and your phone propped side-on.
Move — and watch the form bar
The bar fills as you travel from ~155° toward ~70° at the bottom. Stop short and it tells you; a rep only counts through the full range of motion.
WHAT THE CAMERA WATCHES
- Your elbow angle, live — from roughly 155° at lockout down toward 70° at the bottom. Shallow dips don't count; chest-to-floor reps do.
- Your personal range of motion — after 3 clean reps the counter calibrates its thresholds to your build and depth, so long arms aren't penalized.
- With Pro's depth camera, your body line — if your hips sag or pike away from your shoulders at the bottom, you'll hear "Keep hips level — full plank position."
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.
PRIVATE BY DESIGN
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.
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.
