BACK AND WAIST PART ATHLETIC MACHINE

Document Type and Number:

Japanese Patent JPS59139280

Kind Code:

A

Abstract:

This exercising machine is particularly adapted for execising 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 a resistance force is provided in the form of elongate resilient members. Variable numbers of the elongate resilient members are selectively connectable 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.
