The Thoracic Spine Problem Your thoracic spine, the twelve vertebrae between your neck and lower back, is designed for mobility. It should extend, flex, rotate, and side bend. Modern life forces it into sustained flexion, staring at screens and hunching over devices. The result is pervasive upper back stiffness. Thoracic stiffness affects everything connected to it. Shoulders lose overhead range when the thoracic spine cannot extend. The neck compensates with excessive motion. Breathing becomes shallow. The lower back overworks during rotation. Restoring thoracic mobility has far-reaching benefits. Why the Thoracic Spine Stiffens Sustained flexion: Hours of forward bending creates adaptive stiffness. Lack of extension: Modern life rarely demands thoracic extension. Reduced rotation: Forward-facing activities eliminate rotational variety.

Thoracic Extension JME 171 Sitting in your chair, raise one leg up and in front of you. Then, bend at your knee to find 90 degrees and then return to a straight position. Thoracic Rotation JME 170 Find stability by holding onto the back of your chair or desk. Bend at your knee to raise your leg backward - as high as your are able to - and return to the floor. Thread the Needle JME 172 Sitting in your chair, internally rotate your legs toward each other. Be controlled with your movement and find your end range of motion. Shoulder Blade Mobility JME 189 *Desk Required: With one hand on your desk, bend your upper body forward while maintaining the position of your hand on the desk. Feel a gentle stretch in your forearm and then return to the start. Daily Movement Integration Break up prolonged sitting with thoracic movement. Rotate to look at things rather than only turning your head. Reach overhead regularly. Practice extension throughout the day, not only during exercise. Movement variety prevents the stiffness from returning. Start your 14-day free trial and solve upper back tightness with simplmobility.
