Over-exertion leads to rhabdo
Staff Sgt. Sarah Cox and Airman 1st Class Austin Langlois, 90th Medical Operations Squadron Bioenvironmental Engineering technicians, run on a track on F.E. Warren Air Force Base, Wyo., Aug. 19, 2015. Exercise is recommended by health experts, but over-exertion can lead to a painful condition called Rhabdomyolysis, which is the build up of intracellular material in the blood from damaged muscle tissue.
