Where to put the phone

Three-quarter angle, phone low. Shoulders, elbows and hips visible through the whole transition.

Stand at roughly 45° to the phone. The counter still reads the cycle from the front or the side; the angle only decides how much technique detail the camera can see.

What closes a rep

From forearms, press up to the hands one arm at a time, then lower back to the forearms. The rep closes back on the forearms.

What makes the counter wait

Both arms have to move. A one-arm shuffle does not complete the cycle.

One tip

Lead with either arm; the counter does not require a fixed leading side.

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. Technique detail is measured for the recap and never used to refuse a rep. Why we count and do not grade →
