Methods, systems, and apparatuses for reciprocal muscle activation and release

Abstract

In various embodiments, an apparatus for exercising can include a housing, a first inner tube, a second inner tube, and a compression spring operable to resist motion when compressed. The first inner tube is coupled with a first end of the compression spring and the second inner tube is coupled with a second end of the compression spring. In addition, the apparatus can also include an extension spring inside the housing. Furthermore, a portion of the compression spring and a portion of each of the first and second inner tubes are inside the housing. Note that a first end of the extension spring is coupled with a first handle or loop and the second end of the extension spring is coupled with a second handle or loop. The extension spring is operable to provide resistance during pulling motion away from center of the apparatus.
