Double amputees U.S. Marine Pfc. Isaac Blunt, left, and U.S. Army 1st Sgt. Chris Montera lie still during a yoga class at the Naval Medical Center in San Diego on June 10. Both were gravely wounded in Afghanistan. Other veterans with PTSD or traumatic brain injuries lie on the floor for the one-hour class designed to calm the mind, increase flexibility and improve physical strength.
