Is there really an anti-gravity running machine??
Depends on your definition of anti gravity. If it includes a device the lessens the effect of gravity on you body then this counts. “The physical lifting force generated by the G-Trainer comes from a difference in air pressure around the individual’s body. This anti-gravity effect allows the individual to be lighter on their feet—as if they are defying gravity. The idea of unweighting isn’t new, but Alter-G is the first company to use a pressurized enclosure to provide a counterforce to the person’s body weight, reducing their effective weight on the treadmill surface.” from http://www.alter-g.com/alterg/bd.aspx The CNET video referenced http://cnettv.cnet.com/innovations-make-fitness-fancier/9742-1_53-50005528.html treadmill starts at 2:30 or so.
