How to do it

Setup

Forearms under the shoulders, feet together, body one straight line from head to heels.

Steps

  1. Brace the abs and squeeze the glutes.
  2. Hold the line – no sag, no pike.
  3. Keep the neck neutral, eyes at the floor.

Common mistakes

Hips sagging: squeeze the glutes harder. Hips piked up: the abs stop working; lower to the line. Holding the breath: keep it steady instead.

Breathing

Steady and shallow throughout; never held.
