Abstract: An exercise apparatus comprises a platform that is configured to support a user thereon. The apparatus also comprises at least first and second oscillation mechanisms that are arranged to cause movement of the platform. The first oscillation mechanism is arranged to impart drive to the platform to oscillate in a first frequency range and at a first amplitude. The second oscillation mechanism is arranged to impart drive to the platform to oscillate in a second frequency range and at a second amplitude. The first amplitude can be greater than the second amplitude. Further, each of the first and second oscillation mechanisms can be arranged to generally impart drive to the platform in substantially the same direction. The first and second mechanisms may operate through a drive element that combines drive imparted from the first and second oscillation mechanisms to cause the movement of the platform.
