Can a daily commute double as exercise? A new feature in the Moovit app is betting that it can. His research found that adding roughly a kilometer and a half of walking often reduced transfers and, in some cases, even shortened overall travel times. Rather than focusing on a specific daily step goal, Rabinowitz argues that any increase in walking improves health. By building more activity into routines people already follow, researchers hope commuters can improve their health without finding extra time for exercise.
