Abstract of the Disclosure This exercising machine is particularly adapted for exercising the abdominal muscles of the user and is of a relatively lightweight construction adaptable for home use. The machine includes an exercising lever supported for pivotal movement in an arcuate path during each exercising movement and resistance force means is provided in the form of elongate resilient members. Variable numbers of the elongate resilient members are selectively connect- able to the exercising lever for varying the amount of resistance force being applied to the exercising lever when it is moved by the user. A variable radius cam is interposed between the resistance force and the exercising lever so that the amount of resistance force required to move the exercising lever is varied throughout the various positions of the pivotal arc of movement of the exercising lever.
