Exercise device

An exercise device comprising:

• a base;
• an insert slidably coupled within the base;
• a compression element located within a cavity formed by the base and the insert;
• an extension element extending through the cavity;
• and
• opposing handles connected to opposing ends of the extension element, wherein:
• the compression element is compressed when the opposing handles are moved closer together;
• the extension element is extended when the opposing handles are moved further apart;
• in an equilibrium state of the device with no external longitudinal forces applied to the handles, the compression element is partially compressed and the extension element is partially extended;
• and
• the insert has one or more keys that engage one or more keyways of the base such that, when the one or more keys are fully engaged within the one or more keyways, the compression element is partially compressed to exert outward translational forces to the insert and the base that keep the insert and the base interconnected when no external translational forces are applied to the insert and the base.
