Army Sgt. Mia Lawrence detests running.

“I hate it, yeah,” she said during the classroom portion of a running clinic held here last month.

Lawrence, 25, was trying to tweak her running form with hopes of improving her time on the 2-mile run. She dreads this endurance component of the Army’s annual physical fitness test, which is required of all soldiers.

Lawrence and about a dozen other soldiers had just spent an hour on the Landstuhl Regional Medical Center track, trying to run in a way that felt awkward at first: shortening body strides, landing under the body on the balls of the feet, with feet under the torso, leaning forward and letting gravity do some of the work.
