Regular, easy running for fitness can be a boon to health and well-being, but experts say for safety, joggers especially must keep a spring in their step and an eye on how that foot falls.
"Human beings will naturally walk, sprint or run. Walking is a heel strike, running is a forefoot strike," he said. Jogging is not a slow run. Jogging is actually a different biomechanical behaviour, a hybrid between a walk and a run. Distance runners never land on their heels."
