Kneeling Back Rotation Stretch

  • Beginner
  • Compound
  • Timed hold
  • Back

This dynamic stretch improves thoracic mobility and spinal rotation while opening up the chest and shoulders. It is highly effective for relieving mid-back tension and enhancing core flexibility through a controlled rotational movement.

Muscles worked

  • Obliques
  • Pectorals

  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Start on all fours in a tabletop position with your hands directly under your shoulders and knees under your hips.
  2. Place one hand behind your head with the elbow flared out to the side.
  3. Engage your core to maintain a neutral, flat-back starting position.

How to do it

  1. Inhale as you rotate your torso downward, bringing the elevated elbow toward the opposite wrist.
  2. Exhale as you rotate your chest and elbow upward toward the ceiling as far as your mobility allows.
  3. Follow the movement of your elbow with your eyes to encourage full spinal rotation.
  4. Complete the desired repetitions on one side before switching to the other, or alternate sides each rep.

Form checklist

  • Keep your hips square and stationary to ensure the rotation comes from the mid-back rather than the pelvis.
  • Avoid pulling on your head or neck; let the core and upper back drive the movement.
  • Keep the grounded arm straight and push firmly into the floor for stability.
  • Maintain a slow, controlled tempo without using momentum to force the range of motion.

Pro tips

  • Focus on the mind-muscle connection in the obliques to actively pull your ribcage into the rotation.
  • Think about 'opening your heart' to the side wall to maximize the stretch in the pectorals and anterior deltoids.

Make it harder

  • Perform the stretch with a fully extended arm to increase the lever length and deepen the pectoral stretch.
  • Sit your hips back toward your heels (Child's Pose position) to lock the lumbar spine and isolate the rotation to the thoracic spine.
