Reading the screen
Repchek draws a skeleton over your body. Its colour tells you what the coach is thinking, rep by rep.
-
Get in position
I can see you. Get into your start position and hold still for a second. You hear a whistle, then counting starts. Setting up never costs you reps.
-
Good form
Your form is in range. Keep going. Every green rep is counted as clean.
-
Fix this now
Something broke your form, like hips sagging. The coach tells you what to fix, and that rep is marked in your summary so you can rewatch it.
-
I cannot see you
Part of your body is hidden or out of frame. Nothing is counted or judged until I see you clearly. Move the phone back or turn it side-on.
-
Your back line
Head to shoulder to hip to knee, on side views. Keep it straight. A bend here is what gets backs hurt on deadlifts, rows and push-ups.
