A treadmill was the last machine I was thinking of. I should have made it clear that I was talking about iso-lateral cardio machines such as stairmasters, ellipticals, and arch-trainers which have 2 independent sides.
Obviously usage is the major issue here, but who would you rather lend your car out to, a 100 pound woman who doesn't smoke? or a 350 pound guy who smokes? Certain people w/ certain postural issues decrease the health of cardio machines! Poor cardio machines
