Equipment

Setup

  1. Begin in a tall kneeling position with your knees hip-width apart and your torso upright.
  2. Engage your glutes and core to maintain a neutral pelvis and stable base.
  3. Let your arms hang naturally at your sides with your shoulders relaxed.

How to do it

  1. Inhale as you reach one hand back toward your heel, rotating your torso and following the hand with your gaze.
  2. Exhale as you drive your hips forward, reaching the opposite arm toward the ceiling to create a long line from knee to fingertips.
  3. Inhale to return to the starting upright position with control.
  4. Alternate sides for each repetition, maintaining a slow and steady tempo.

Form checklist

  • Keep your hips pushed forward throughout the movement; do not sit back on your heels.
  • Rotate through your upper back (thoracic spine) rather than arching solely from the lower back.
  • Keep your core braced to stabilize the spine during the rotation.
  • Ensure your gaze follows your reaching hand to facilitate full neck and upper back mobility.

Pro tips

  • Focus on the 'reach and lift' sensation in the chest to maximize the stretch in the obliques and anterior deltoids.
  • Squeeze the glutes of the reaching side to provide a stable anchor for the rotation and protect the lumbar spine.

Make it harder

  • Increase the range of motion by attempting to touch the floor behind your feet instead of your heels.
  • Add a 3-second isometric hold at the point of maximum rotation to challenge balance and core control.
