Abstract: In a basic configuration, the present system includes an adjustable top portion or platform, one or more lower portions or risers and one or more resilient members placed between the riser and the platform. Preferably the resilient members have a sufficient height to space the platform slightly above the riser, and the resilient members are partially compressible to absorb the impact when a user steps atop the platform. In preferred embodiments, the platform and/or riser include a variety of locations in which the resilient member or members may be placed or arranged to provide various levels of cushioning and/or balancing of the platform over the riser. Preferably the multi-exercise system can be used as a standard horizontal platform, as an angled platform, as a balancing platform, or a resilient member-mounting riser for aerobic exercises, stretching, yoga, balancing or exercises exercising the sole or arch of a foot.
