I first experienced a WBV (Whole Body Vibration) machine at a friend's house. He and his mother raved about the benefits. I did some reading of my own on WBV and decided to try it for myself. It feels like getting a Swedish massage once you go through the various exercises in the leaflet, wish there were more. There are websites you can get to and find WBV exercise charts. I've only had the device for a few weeks, will update later on results.
