Thoracic Extension on Foam Roller

Lie on your back with a foam roller placed across your upper back, just below your shoulder blades, knees bent and feet flat on the floor. Support your head with your hands, elbows in, and let your hips stay low while you arch your upper back over the roller. Keep your lower back from arching along with it by tightening your stomach and keeping your hips down; the movement should stay in your upper spine, not your lower back. Walk the roller a few centimetres up or down between reaches to work different segments of your upper back.
