How it works

  1. 1Prop your phone up sideways, about 2 meters away, so your full side profile fits in the frame.
  2. 2Lie down in sit-up position. The tracker locks on when it sees your shoulder, hip and knee.
  3. 360 seconds on the clock. Full reps only — down then all the way up. Most reps wins.
