The iVibration Whole Body Vibration Machine provides isometric anaerobic exercise through the use of whole body vibration. The iVibration improves upon this vibration by utilizing the Triangular Oscillating System (T.O.S.). The Triangular Oscillating System provides a gentle rocking motion rather than just up and down movement as a way of reducing the impact on joints and ligaments. There is a substantial difference between T.O.S. and “piston” or “tri-planar” vibration used by many other vibration machines that can cause more stress to the body. The T.O.S. utilized by the iVibration generates systematic involuntary muscle contraction with less G force than the piston driven tri-planar systems, designed to cause less stress on the joints and ligaments. This pleasant rocking motion causes the brain to tell the muscles of your body to actively contract to maintain equilibrium, thus creating a therapeutic and muscle toning workout.
