ng-fitness-breakthrough-in-decades.aspx Wonderful Dr. Mercola has a lot of information on the PowerPlate machine but they cost about $5,000 but they do wonders and are well worth the money. I'd buy one except I'm paying off my son's college loan since he had cancer and hasn't been working. But, at some point, I'd sure like one.
The above Link is just one of Dr. Mercola's on the machine as he has more information and on YouTube.
