The present disclosure relates generally to the field of arm exercise apparatus, and, more particularly, to an arm exercise apparatus using elastic materials to provide resistance.
Physical fitness is widely recognized as a key component to good health. Numerous kinds of exercise equipment have been developed to facilitate people's physical exercises. Conventional arm exercise equipment generally utilizes weights to provide resistance to user motions. As weights and hence gravity force is one dimensional, such conventional exercise equipment have limited freedom of motion. As such what is needed is an exercise apparatus that can provide resistance to large range of motion for arm exercises.
