Foam Roller: Upper Back (aka Thoracic Spine): For after a day at the computer. Start lying face up with the roller underneath your shoulder blades. Interlace your fingers and place them behind your head to support the weight of your skull. Push with your feet to roll up and down your upper back. Roll from shoulder blades to the mid-back (keep the roller where you have ribs) for 30 to 60 secs.
