A brisk walk is about 3 miles an hour, which is faster than a stroll. To get any real health benefits you need to walk over 3 mph for 20 minutes or longer in one stretch. While walking slower or in short bursts has some benefit, you need to get your heart rate up (and burn more calories) for a real cardio benefit.
