ABSTRACT:
An exercising device is provided to exercise the knee and ankle by providing straps attached to elastic members wherein the operator's foot is firmly grasped and the entire apparatus is held in place by the user attaching it to the back of a chair with the user sitting in said chair and moving his ankle and knee against the tension created by the invention on said knee and ankle. A strap forming a noose is attached to the ends of the elastic members. A force on the noose by a user's limb causes the noose to tightly engage the limb of a user.
