Pull-up set analyzed by AI form check

A strict pull-up set filmed in the gym, footage HyperBody's AI form check scores rep by rep: full hang, chin over bar, kipping, and tempo.

What the form check measures on this lift

Bar clearance
Our algorithm estimates the bar height from your hands and checks on every rep whether your head actually cleared it, so half reps get counted as half reps.
Lateral swing
Side-to-side body sway is measured relative to your shoulder width, flagging sets where you drift around instead of pulling straight.
Front-back swing
Kipping and momentum show up as front-to-back movement, which is measured separately and flagged when it passes the strict pull-up standard.
Elbow symmetry
The minimum elbow angle each arm reaches at the top is compared left versus right, catching one arm doing more work than the other.
Shoulder symmetry
Left and right shoulder angles are compared through the pull, flagging uneven pulling patterns worth over 15 degrees.
