Hip Thrust Rep Counter
Stop counting in your head. Point your phone at yourself and every full-range hip thrust counts itself — sets, reps, and PRs logged automatically while you train your glutes and hamstrings, with core assisting. Free, in your browser, no account needed.
▶ Start Counting FreeHOW TO DO A PROPER HIP THRUST
Setup Rest your upper back on a bench/couch, side-on to the camera, feet flat.
- Drive through your heels and lift your hips until your body is flat from knees to shoulders.
- Squeeze your glutes hard at the top.
- Lower under control.
This is the same instruction sheet you’ll find on the ⓘ panel inside the app — with an animated demo next to it.
HANDS-FREE IN THREE STEPS
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 hip angle (shoulder → hip → knee) in real time, entirely on your device. No wearables, no clickers. A bench or couch behind you; bodyweight first, a barbell across your hips later.
Just work — the counter does the counting
A rep banks at the bottom (~160°) and re-arms when you return toward ~100°. Half reps don’t count, and after 3 clean reps it calibrates to your personal range of motion.
WHAT MAKES A REP COUNT
- Your hip angle, live — from roughly 100° at the bottom up toward 160° at full extension. Partial bridges don't bank; a real lockout does.
- Your personal range of motion — after 3 clean reps the counter calibrates to your setup and build.
- The top of every rep — finish soft and the form cue pushes back: "Drive hips fully up."
COMMON HIP THRUST MISTAKES
Overarching at the top
The finish is a glute squeeze, not a back bend. Ribs down, chin tucked, and stop when your hips line up with your knees and shoulders.
Pushing through your toes
Toes-first drive sends the work to your quads. Plant your heels under your knees and press the floor away through them.
Bench in the wrong spot
The pad should sit right under your shoulder blades. Too high chokes your range; too low turns it into a glute bridge.
Fast, bouncy reps
Speed hides weak lockouts. Pause one beat at the top with your glutes squeezed hard — that beat is the exercise.
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 a barbell for hip thrusts?
No — bodyweight hip thrusts off any sturdy bench or couch are the right starting point. Add weight across your hips later and log it for PR tracking.
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.
