Description

This stretch involves lying on your side with your arms extended in front of your chest, and then opening and closing your top arm like a book, hence the name 'Open Book Stretch'.

How to Do Open Book Stretch

1
Setup
Lie on your left side with your knees bent at a 90-degree angle, stacked directly on top of each other. Keep your hips aligned and your left arm extended straight out in front of your chest.
2
Setup
Stack your right arm directly on top of your left arm, palms together, maintaining a neutral spine.
3
While keeping your knees and hips stacked, slowly lift your right arm and open it towards the right side, rotating your upper back and head to follow your hand.
4
Continue to open your right arm until your right shoulder blade is close to or touching the floor, feeling a stretch in your chest and thoracic spine. Take a deep breath here.
5
Exhale as you slowly return your right arm to the starting position, stacking it back on top of your left arm.
6
Complete all repetitions on one side before switching to the other side.

Tips

Keep your lower body stable by pressing your knees together throughout the movement to isolate the thoracic spine rotation.
Focus your gaze on your moving hand to encourage a deeper rotation through your neck and upper back.
Inhale as you open your arm and exhale as you return, using your breath to deepen the stretch and relax into the rotation.
If your top knee lifts, place a yoga block or pillow between your knees to help maintain stability and prevent your hips from rotating.

Common Mistakes

×Allowing the hips to rotate with the torso reduces the intended thoracic stretch; fix this by actively pressing your knees together and keeping your hips stacked.
×Rushing the movement and using momentum rather than controlled rotation limits the effectiveness of the stretch; fix this by moving slowly and deliberately, focusing on spinal articulation.
×Not following the hand with your gaze restricts neck and upper back rotation; fix this by consciously turning your head to watch your moving hand throughout the opening phase.
