Burpee Form Check
Is your burpee actually good? Prop your phone up and find out — GoodReps watches your knee angle (hip → knee → ankle) live and scores every rep as you train your chest and quads, with shoulders, core and glutes assisting. Free, in your browser, processed entirely on your device.

Setup Turn side-on to the camera with room to drop down and kick back.
- Squat, plant your hands, and kick your feet back to a plank.
- Optional push-up, then jump your feet back in.
- Explode up into a jump, reaching overhead. Reset fully each rep.
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 BURPEE
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 knee angle (hip → knee → ankle) in real time, entirely on your device. No wearables, no sensors. No equipment — just room to drop down and jump back up.
Move — and watch the form bar
The bar fills as you travel from ~165° toward ~80° at the bottom. Stop short and it tells you; a rep only counts through the full range of motion.
WHAT THE CAMERA WATCHES
- Your full descent and rise, live — from roughly 165° standing through the crouch and plank and back. Skipped phases don't bank; the whole cycle does.
- Your personal range of motion — after 3 clean reps the counter calibrates to your pace and depth.
- The finish position — land soft but stand ALL the way up; the form cue is firm: "Full reset to standing."
COMMON BURPEE MISTAKES
Skipping the plank
Kicking back halfway and bouncing forward again cuts the burpee's engine out. Hit a real plank — body straight — every rep.
Sagging through the middle
Flopping to the floor with a soft core is how lower backs get grumpy. Brace before you drop and keep the line.
Never standing tall
Hunching into the next rep shortchanges the reset. Finish upright — hips open, chest up — before you go again.
Redlining rep one
Burpees punish bad pacing like nothing else. Find a rhythm you could hold for twice your set and build from there.
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 burpees?
No — just enough floor to drop into a plank and enough ceiling to jump. Your phone watches from the side.
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.
