The Tri-Flex is the first two motor, three motion machine of its kind. Not only does it have two built-in motors but it also offers three kinds of vibration. Traditional vibration plates only have one vibration mode. Tri-Flex provides three different types of vibration modes. The first is triangular oscillation which provides a whole body vibration from head to toe. The second is spiral vibration, which creates a smooth, elliptical motion for muscle recovery, rehabilitation, and regular workouts. The third is dual mode, combining both modes transversely. This is optimal for fitness, excellent for cellulite targeting and intense workouts. These three vibration modes are designed to meet your needs whether they are for professional or home use.
