Standing Side Stretch

This lateral flexion exercise improves spinal mobility while lengthening the obliques, intercostals, and latissimus dorsi. It is highly effective for relieving side-body tension and improving overall torso flexibility.

Equipment

  • Body weight

Setup

  1. Stand with your feet hip-width apart and your weight evenly distributed across both feet.
  2. Engage your core and keep your shoulders relaxed, away from your ears.
  3. Raise your right arm straight up toward the ceiling, palm facing inward.

How to do it

  1. Inhale to find length in your spine, then exhale as you lean your torso directly to the left side.
  2. Reach your right arm over your head while allowing your left hand to slide down your outer thigh for support.
  3. Hold the peak stretch for 1-2 seconds, focusing on a deep stretch along the right side of your body.
  4. Inhale to return to the center, lower the right arm, and repeat the movement on the opposite side.

Form checklist

  • Keep your hips square and avoid rotating your chest toward the floor.
  • Maintain a 'flat' profile, imagining you are moving between two panes of glass.
  • Keep your neck neutral and your gaze forward to avoid straining the cervical spine.
  • Ensure both heels stay firmly planted on the floor throughout the stretch.

Pro tips

  • Focus on pushing your rib cage away from your pelvis to maximize the space between your ribs and hips.
  • Breathe deeply into the side of the rib cage to expand the intercostal muscles from the inside out for a deeper stretch.

Make it harder

  • Cross the leg of the stretching side behind the other leg to increase the stretch through the hip and IT band.
  • Clasp both hands together overhead and gently pull the top wrist to increase the leverage and intensity of the lateral pull.
