Abstract
An elastic resistance type exercising device having a single length of latex rubber surgical tubing whose two ends are formed into size handle loops by the use of leather fasteners. The handle loops are sleeved with vinyl tubing, and plugs are inserted in each of the open ends of tubing, that have twice passed through the fasteners to form the loops, to prevent the tubing from being pulled out of the fasteners. A user grasps the handle loops or secures them about his ankles and pulls against the elastic resistance. Two additional flexible sleeves are slidably mounted over the portion of the elastic tubing between the fasteners.
