It doesn’t seem to matter whether a person runs on the streets outside around his home or whether he looks to his local gym and uses a commercial treadmill to get fit, both options are good for improving health. There are a few things to remember, however, when taking advantage of a treadmill as there are different forces on the body that don’t exist on a regular road. When running on a flat treadmill, a person is actually running downhill due to the motion of the machine itself. Therefore, it’s advisable to increase the elevation of the treadmill to at least one percent to compensate.
