what confuses me is how crazy we think this is, even though the treadmill seems normal. why do you need a machine to help you run in the first place, how bout you just run? raining, put on a jacket. snowing, put on a jacket! world flooded from global warming caused by by-products of creating the energy needed to "walk", learn to swim! IMO this and treadmills are both as crazy as madcrawdad's tater-mitts.
