This is a relatively new breed of vibration machine that was introduced to North America in the last few years. The dual machines have 2 separate motors and 2 separate drive motion mechanisms. They typically use a larger motor for oscillation motion and a smaller motor for a Spiral Rotational motion. This motion is quite different from oscillation as the plate that the user stands on does not move up or down, as with oscillation. Spiral Rotational motion moves the plate forward and back and side to side. These dual machines also allow the user to combine both the oscillating motion in conjunction with spiral rotational together to create a third unique motion style that is very similar to Triplanar motion. These dual machines offer the user all the benefits of both styles of vibration machines combined into one unit. These machines are very effective for weight loss, strength training, bone density increases, hormonal increases, lymphatic drainage, improved blood circulation and body shaping or toning. Certainly this new style of dual machine could be considered the new generation of vibration machine as they offer user all the many great benefits of vibration training rolled into one single device.
