Outdoor running

In treadmills the inclined featured can be adjusted as per the user need so the stress on foot is less. Running on a treadmill is comparatively easier as it is a kind of aided running. When you put your heal forward on a treadmill the moving belt brings your landed foot behind which makes it easier.
