The Open Book stretch is a gentle thoracic mobility drill I give patients to help reduce upper and mid-back stiffness and restore clean rotational movement. This exercise works well for posture-related tightness, desk fatigue, or anytime the mid-back feels restricted.

How to Perform It:

• Lie on your side with your knees bent and stacked

• Reach your top arm forward, then slowly open it across your body

• Allow your chest to rotate toward the ceiling

• Keep your knees together and stable

• Follow your hand with your eyes and breathe normally

Common Mistakes to Avoid:

• Forcing the stretch too far

• Letting the knees separate

• Moving too quickly

• Holding your breath

Recommended Dosage:

• 10 slow reps each side

• 1–2 sets per day as needed

This exercise is part of the movement-based approach we take at Mountain Movement Chiropractic in Spearfish, SD. If you’re a patient of Dr. Zach Hansen, use this as directed in your care plan to support better mobility and long-term spinal health.
