V-Ups

Where to put the phone

On your back, phone low, whole body in frame including the hands overhead.

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

Fold torso and legs together, reach for the feet, lie back out. The rep closes when you are flat again.

What makes the counter wait

Lifting only the legs or only the shoulders is a different movement. Both halves have to fold.

One tip

Slightly bent knees are fine. The counter reads the fold, not the knee angle.

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 →
