Setup
- Stand with your feet shoulder-width apart and your spine in a neutral, tall position.
- Raise your right arm straight overhead, reaching your fingertips toward the ceiling.
- Place your left hand on your hip for stability or let it hang naturally at your side.
How to do it
- Inhale deeply, reaching upward to create space in the ribcage and lengthen the triceps and lat.
- Exhale as you slowly rotate your upper torso to the left, reaching the right arm slightly back and across the midline.
- Hold the peak stretch for 2-3 seconds, focusing on the pull through the side of your torso.
- Inhale to return to the center with control, then repeat for the desired reps before switching arms.
Form checklist
- Keep your hips facing forward; the rotation should occur in the mid-to-upper back (thoracic spine).
- Keep the reaching arm fully extended and aligned with your ear.
- Avoid shrugging the reaching shoulder; keep the shoulder blade pulled down away from your ear.
- Maintain a slight bend in the knees to prevent lower back arching.
Pro tips
- Focus on 'breathing into the ribs' of the reaching side to expand the intercostal muscles and deepen the internal stretch.
- Imagine you are trying to touch a point on the ceiling slightly behind you to maximize the diagonal tension through the obliques.
Make it harder
- Cross the leg of the reaching side behind the other leg (curtsy stance) to increase the stretch along the entire lateral chain down to the hip.
- Hold a light yoga block or water bottle in the reaching hand to provide gentle traction and increase the pull on the lats.
