Recent fitness trends, like "Zone 2" training and hitting 10,000 steps a day, are driving the conversation around the "best" method of exercise, and what it means to stay fit without intense workouts.
Japanese walking is one of the latest of these trends, although this form of exercise is not exactly new.
Decades ago, researchers from Japan compared the benefits of interval walking (switching between fast and slow paces) to keeping the same speed the entire time.
Their findings indicated that moderate-intensity interval walking could protect against certain "age-associated" effects, including increases in blood pressure, weakening of thigh muscles and a reduced ability to exercise in the first place.
