Chest excusion: Normally our chest expands 2-5 " when we take a deep breath. if you smoke or have a condition that lmits exapnsion of the lung, autoimmune disease or ankylosing spondylitis may be less. Stretching exercises may help, as may chest exercises http://www.rehab.research.va.gov/mono/lowerlimb/chest.pdf https://www.youtube.com/watch?v=Kp8WK4hFsTs
