Patent attributes
An exercise system comprising an extension section and a base section. The base section comprises a support assembly, a sleeve assembly, and a resilient member. The resilient member is arranged to resiliently oppose movement of the sleeve assembly in a compression direction relative to the support assembly. The extension section is detachably attachable to the sleeve assembly. The exercise system is operated in at least first and second configurations. In the first configuration, the extension section is detached from the sleeve assembly. In the second configuration, the extension section is detachably attached to the sleeve assembly such that the resilient member resiliently opposes movement of the sleeve assembly relative to the support assembly in the compression direction.
