Live AI
form coaching.
Every rep on the record.
Therox is an AI form tracker that counts your reps and checks your form using your phone camera, on device. Your coaches' videos in one vault, and a crew that keeps you honest.
Good form isn't a feeling. It's a line you can see, rep after rep.
Prop your phone and start your set. Therox counts each rep, turns the joints that drift red, and calls out the fix while you move. Play the set back and it draws the angle each check judged on you, green or red. The video never leaves your phone.
- 01
Depth
How low each rep goes. A short rep shows up on the check as it happens, not after the set.
- 02
Lockout
Full extension at the top of every rep. The check lights up when you stop short.
- 03
Body line
Hips in line with your shoulders and ankles. A sagging or piking plank turns those joints red on screen.
- 04
Lowering
How long the way down takes. Rush it and the cue is "slow the way down".
- 05
Drive
How long the way back up takes. Grind it out and the cue is "drive up faster".
