Claim:
1. An exercise device, comprising: a multi-layer platform, and a plurality of anchoring elements, wherein the platform includes a soft upper layer, a rigid lower layer and a plurality of cavities passing through each of the upper layer and lower layer, wherein the anchoring elements include ends removably connectable to the cavities of the platform, wherein the rigid lower layer and the ends comprise matching surfaces allowing mutual connection of the platform and the anchoring elements, wherein the rigid lower layer comprises at least multi-layer wood, wherein the platform comprises a soft third layer, associated with the rigid lower layer, to prevent the platform from slipping relative to a floor surface, wherein the third layer includes a plurality of recesses positioned beneath the plurality of cavities, the recesses being larger than the cavities such that an upper surface of each recess is partly formed by a lower surface of the lower layer; wherein the ends include protuberances shaped to pass through the cavities in the upper layer and lower layer and, when aligned with the third layer, to be rotatable in the recesses with respect to the cavities to be positioned under the lower surface of the lower layer to prevent withdrawal of the anchoring elements without further rotation of the protuberances to again align with the cavities.
