How to do it

Lay down with your back on the floor. Place a foam roll underneath your upper back, and cross your arms in front of you, protracting your shoulders. This will be your starting position.
Raise your hips off of the ground, placing your weight onto the foam roll. Shift your weight to one side at a time, rolling over your middle and upper back. Pause at points of tension for 10-30 seconds.

When to stop

Stop and rest if you feel chest pain or pressure, are more short of breath than you'd expect, feel dizzy or faint, or have sudden pain. If chest pain or faintness doesn't pass when you rest, call 911.
