This seated rotational stretch improves spinal mobility and relieves tension in the erector spinae and obliques by decompressing the vertebrae. It is highly effective for reducing lower back stiffness and improving functional rotation.

Setup

  1. Sit upright on the edge of a flat bench with your feet flat on the floor, hip-width apart.
  2. Maintain a neutral spine with your chest lifted and shoulders relaxed.
  3. Place your right hand on the bench behind your right hip for support.

How to do it

  1. Inhale deeply to lengthen your spine toward the ceiling.
  2. Exhale as you rotate your torso to the right, placing your left hand on the outside of your right thigh.
  3. Hold the position for 20-30 seconds, breathing deeply into the stretch to expand the ribcage.
  4. Slowly return to the starting position and repeat the movement on the opposite side.

Form checklist

  • Keep both sit bones firmly planted on the bench throughout the rotation.
  • Lead the movement with your chest and shoulders rather than just turning your head.
  • Avoid slouching or rounding the lower back; maintain a tall, vertical posture.
  • Keep your shoulders depressed and away from your ears.

Pro tips

  • Use the hand on your thigh as a gentle lever to deepen the stretch, but never force the rotation beyond your natural range of motion.
  • Focus on 'growing taller' with every inhale to maximize the space between your vertebrae before rotating further on the exhale.

Make it harder

  • Cross the leg of the side you are turning toward over the opposite knee to increase the leverage and stretch depth in the glutes and lower back.
  • Reach your back arm further across the bench to engage the upper lats and deepen the thoracic rotation.
