Knee Push Up Counter: Hands-Free Knee Push Up Rep Counting

Kneeling lets you build toward full push ups, and this knee push up counter keeps the tally. The phone lies low on the floor and watches your elbows bend, so your eyes can stay on the ground.

Both arms are read together, so there's no one-arm mode. Get your knees down and your arms straight during the five-second countdown, then the coach counts each rep out loud.

Phone setup

Lay the phone sideways (landscape) on the floor, with the lens low, about 2 meters (6 feet) away. Your whole body, head to feet, has to fit inside the frame.

Turn your body halfway between side-on and facing the phone, so both arms stay in view. Keep your knees on the floor and your body straight from your knees to your shoulders.

• Settle into the top position and glance at the preview to confirm your hands, knees and head are all inside the frame.

Form cues

• Keep one line. Run your body straight from your knees to your shoulders, with your hips neither sagging nor poking up.
• Stack wrists under shoulders. Pressing from directly beneath your shoulders keeps every rep a clean, straight push instead of a wobble forward.
• Lower until your elbows bend. The bottom of the rep is a clear elbow bend, and a shallow dip stops short of it.
• Press all the way back. Straight arms at the top finish the rep, so reset fully before you head down again.

Common mistakes

• Sagging at the hips. Squeeze your glutes and brace your core so your hips stay in line with your knees and shoulders.
• Dipping only a little. A dip that stops short of the far position isn't counted. Lower until your elbows are clearly bent, then press back up to straight arms.
• Squaring up to the phone. Facing the lens head-on folds your arms toward the camera. Turn halfway toward side-on so both elbows stay in view.

How FitnessBruh counts it

FitnessBruh measures the angle at your elbow, from shoulder to elbow to wrist. Straight arms at the top are the start, the bottom with your elbows bent is the far position, and a rep finishes when you press back to straight arms. The number is spoken as you return to the start.

Both arms are read together. There's no one-arm mode for knee push ups, so bend and press with both sides at once. A rep that never reaches the far position isn't counted.

Counting only starts once you've been down in position for a moment, so kneeling down before the set adds no rep. It also needs a steady view of your shoulders and hips. Get up mid-set and counting stops until you're back down in position.
