How to do it

Setup

On one forearm, elbow under the shoulder, feet stacked; hips lifted into one straight line.

Steps

  1. Hold the line from head to heels.
  2. Keep the hips stacked – no rolling forward or back.
  3. Switch sides without dropping through the middle.

Common mistakes

Hips sagging toward the floor: push the floor away, lift the waist. Rolling the chest toward the ceiling: shoulders stacked. Head hanging: neck in line.

Breathing

Steady throughout; never held.
