Where to put the phone

Face the phone, whole body in frame, with room behind you for the step.

What closes a rep

Step back and drop the back knee low, then stand back up. The rep closes when you are standing again.

What doesn’t count

Alternate legs on every rep. A second rep on the same leg, a shallow lunge or a hand pushing on the thigh is refused, not counted.

One tip

Each side counts as one rep.

After the set

Every set ends with the same recap: reps counted, time, pace, the longest run, pauses, whether the second half held up, and the camera angle the phone actually saw. Detail beyond the movement’s own rules is measured for the recap, never used to refuse a rep. Why we count and do not grade →
