Exercise Tubing for High Intensity Interval Training and Methods of Use

An exercise apparatus, comprising:

• a pair of elastomer tubing devices, each elastomer tubing device having a resting length, a resting inner diameter, a resting outer diameter, and a tube thickness, each elastomer tubing device stretchable beyond the resting length and further having a first end comprising a segment having a second outer diameter greater than said resting outer diameter for forming a hand grip for a user, and an opposing end including an anchor portion to enable said opposing end to be releasably attached to a fixed mount, at least one of the elastomer tubing devices comprising a center-loaded portion within said inner diameter disposed between said opposing tube ends and having a mass,
• wherein said pair of elastomer tubing devices are independently affixable to one or more fixed mounts at a first distance between said opposing ends and a second distance above a ground level to permit independent or tandem oscillation of said elastomer tubing devices by the user, said elastomer tubing devices being stretched a predetermined distance beyond the resting length and maintained at said predetermined distance during said oscillation, the mechanical impedance of said elastomer tubing devices being adjustable by the user working against inertia generated during said oscillation.
