The concept of Whole Body Vibration was developed for the Russian Cosmonauts in an effort to combat muscle atrophy, bone density loss, and blood clotting during extended periods of exposure to zero gravity. Decades of research and endorsements indicate that this innovative machine produces effective results. The immediate effect of Whole Body Vibration (WBV) is to stimulate the body's physical response to vibrations by vigorously activating reflexive muscle contractions 20-50 times per second. This translates to a more efficient workout, strengthening muscles, increasing flexibility, improving bone density, and may provide many other benefits in a variety of areas.
