Dumbbell Row Rep Counter
Stop counting in your head. Point your phone at yourself and every full-range dumbbell row counts itself — sets, reps, and PRs logged automatically while you train your back and biceps, with shoulders and core assisting. Free, in your browser, no account needed.
▶ Start Counting FreeHOW TO DO A PROPER DUMBBELL ROW
Setup Turn side-on to the camera, hinge forward ~45°, back flat, weights hanging.
- Pull the weights up to your chest, driving your elbows back.
- Squeeze your shoulder blades together at the top.
- Lower under control to a full stretch.
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 elbow angle (shoulder → elbow → wrist) in real time, entirely on your device. No wearables, no clickers. One dumbbell (or any weight you can hinge over) — log it and track PRs.
Just work — the counter does the counting
A rep banks at the bottom (~55°) and re-arms when you return toward ~145°. Half reps don’t count, and after 3 clean reps it calibrates to your personal range of motion.
WHAT MAKES A REP COUNT
- Your elbow angle, live — from roughly 145° hanging long up toward 55° at the pull. A shrug isn't a row; the pull has to travel.
- Your personal range of motion — after 3 clean reps the counter calibrates to your build, so long arms aren't penalized.
- Whether the weight actually reaches you — stop the pull early and the form cue is waiting: "Pull to chest."
COMMON DUMBBELL ROW MISTAKES
Standing up out of the hinge
As sets get hard, the torso creeps upright and the row turns into a shrug. Set your ~45° hinge and keep it — the camera sees you side-on, so it shows.
Pulling with the arm only
The row starts at the shoulder blade. Think "elbow to the ceiling" and squeeze your back at the top, not your hand.
Rounding your lower back
A flat back is the whole foundation. Brace your core before the first pull and keep your chest proud through the set.
Short, jerky pulls
Momentum robs the rep. Let the weight hang to a full stretch, then pull smooth — full range banks, half range doesn't.
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 bench to count dumbbell rows?
No — GoodReps tracks the standing bent-over row: hinge forward about 45°, weight hanging, and pull. Any single dumbbell, kettlebell, or heavy object works.
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.
