Few of us think we need a course in walking any more than we’d need a course in breathing, but Jonathan FitzGordon, a yoga teacher and owner of Yoga Center of Brooklyn, insists that most Americans don’t have a clue how to step, a problem he first noticed among his yoga students.

“People would enter with terrible posture,” he said. “Then they’d do beautiful yoga, and listen to everything I said about alignment. As soon as class ended, they went straight into the bad posture.”

To help students take their practice into the street, Mr. FitzGordon incorporated walking lessons into his yoga classes, as well as teaching small group and individual sessions. His clients are mostly people who have visited doctors, chiropractors and massage therapists in search of relief for muscle or joint pain.
