<p>A physical exerciser of the type having a spring enclosed by a telescopic tubular system so that contraction of the system is resisted by the spring. Flexible connecting elements connect the ends of the system on opposite sides so that pushing exercises can be performed by pushing handles at the ends together and pulling exercises by pulling the flexible elements apart. According to the preferred form of the invention each flexible connecting element is continuous in the form of two runs guided round one or two rolling members mounted in handles at the ends of the system. Either one or both runs can be pulled giving variation in the force and movement distance. According to another feature a greater contraction distance of the telescopic system is achieved by an arrangement having a central tube beyond the ends of which the ends of the spring extend and further end tubes accommodating the ends of the spring and connected to the handles so that the majority of the interior of the handles also accommodates part of the telescopic movement.</p> |
