A physical exerciser is provided which utilizes a pair of compression springs. The springs are maintained in a spaced apart, parallel, side-by-side, straight state by an assembly comprising an inner guide member and an outer tube circumscribing said member. The springs extend longitudinally in troughs formed in the peripheral surface of the elongate guide member. The troughs extend parallel to the longitudinal axis of the tube. The tube holds the springs in place in the troughs. The assembly further provides a stop at one end of each spring, to fix that end against displacement. A pair of tubular handles are mounted on the tube, one at each of the tube's ends. Each handle includes a pin extending transversely across the free end of one of the springs. Suitable slots are provided in each end of the guide member and tube, so as to allow the handles to slide inwardly, each such handle acting to compress one of the springs. There are thus duplicate means at work in the single tube-each means comprises a spring, its stop, the handle and pin which can compress the spring, and the slots which permit the pin to travel. The spring, pin and slots of each means lie in a common plane. The two common planes for the two means are disposed at 90 DEG to each other. The exerciser thus has two handles, each operating independently against its own spring, which may be forced inwardly simultaneously and be brought close together, for better muscle development.
