Abstract

Abstract Exercising machine having a plurality of resilient rods which are flexed and resist movement of a person using the machine. Forces are exerted on the resilient rods through cables to which a variety of attachments such as hand grips, foot stirrups and a sliding bench can be connected to exercise different parts of the body. The rods can be used in any combination to suit the requirements and physical abilities of the person using the machine.
