A portable exercising apparatus comprising a single elastic tubing, a sleeve slipped over each end thereof and exposing a substantial length of said tubing at its ends, means for receiving a folded portion of said tubing so that an adjustable loop will be formed for receiving hands or legs of a user, said means comprising S-shaped hook having a pair of substantially closed eyelets with said hook positioned near an end of said tubing, said tubing hooked through the eyelets thereof forming the adjustable loop in the portion of the tubing having one of said sleeves thereon, a ring slidably movable along the length of said tubing for connecting said tubing to a projection from a stationary object, said sleeves being mounted on the tubing forming the loops adjacent each hook for safe exercising without friction burns from the tubing, and a second sleeve on each end of said tubing for preventing the end of said tubing from slipping out of said hook, said hook maintaining sufficient friction between the looped tubing within the eyelets of said hook for preventing unwanted changes in the size of the loop once the exerciser sets the loop size for any of his limbs.
