How do I film my bench press for a form check?

Place your phone a few meters away at roughly bench height, angled so your whole body and the bar stay in frame for the entire set. A side or 45 degree view works, and one set of 3 to 10 reps is enough.

Can AI detect bouncing the bar off my chest?

Yes. The analyzer tracks bar velocity through every descent and looks for the sharp reversal that happens when the bar bounces instead of being pressed, then tells you exactly which reps did it.

What does the bench press report include?

Per-rep verdicts on range of motion, bar drift, elbow flare, descent speed, bounce detection, left-right symmetry, and shoulder stability, plus tempo timing and cues ordered by what matters most.

Does it work without a spotter or power rack?

Yes. The form check only needs a phone video of your set. It reads your joint positions directly from the footage, so any bench setup works as long as you and the bar are visible.

AI form check

AI Bench Press

Film a set of bench, upload it, and the AI scores every rep. It tracks your bar from lockout to chest and back, measuring range of motion, elbow angles, and how controlled the descent really is.

Check my form

Every rep, scored

What the AI checks on your bench press.

Range of motion: Bar travel is measured from lockout to the bottom on every rep, so short reps that never reach the chest get flagged individually.
Bar drift: Side-to-side bar drift is tracked relative to your shoulders through each rep, catching a bar that wanders off its groove.
Elbow flare: The angle between your upper arm and torso is measured at the bottom. Elbows flaring past about 55 degrees get flagged as a shoulder risk.
Descent control: Each descent is timed. A drop faster than half a second is flagged as uncontrolled, and a velocity spike at the chest is flagged as a bounce.
Left-right symmetry: Left and right elbow angles are compared on every rep, so one arm flaring or lagging behind the other shows up in the report.
Shoulder stability: Your shoulder position is tracked through the set. Shoulders shifting around on the bench instead of staying pinned get flagged.

Common faults

Mistakes it catches.

Bouncing off the chest: Using the chest as a springboard. The AI detects the velocity reversal at the bottom and flags the reps that bounce.
Cutting reps short: Not bringing the bar all the way down. Partial reps are the most common flag on heavy sets.
Flaring the elbows: Elbows drifting out toward 90 degrees at the bottom, which shifts stress onto the shoulder joint.
Dropping the bar too fast: An uncontrolled descent that relies on the bounce instead of the chest and triceps to reverse the weight.
