Abstract
A push-up exercise apparatus for simultaneously exercising the muscles of the upper body, wrist, and forearms is disclosed. The apparatus comprises a base to elevate the hands of a user above the underlying surface, and at least two hand exercisers connected to a rigid member that is coupled to the base. The hand exerciser includes a pair of elongated fingers, a torsion spring pivotally connected between the fingers, and a spring band to limit spring expansion.
Claims22
A push-up exercise apparatus, comprising:
- a. a base;
- b. at least two hand exercisers, each hand exerciser including a resilient coil spring having a first and second end that both extend perpendicularly away from a pivot axis to form an acute angle between said ends, a spring band in communication with each spring end to limit spring expansion, and a finger grip at the first end of said spring;
- and
- c. a rigid member having a means for removably coupling said rigid member to said base and a means for coupling said rigid member to the second ends of said hand exercisers;
- whereby said rigid member is no more than two feet above a support surface.

A push-up exercise apparatus for use by a person performing push-ups, comprising:
- a. a means for stably elevating the hands of said person no more than two feet above the underlying surface such that the chest of said person faces the underlying surface;
- and
- b. at least two hand exercisers coupled to said elevating means, in which each hand exerciser includes a resilient coil spring having a first and second end that both extend perpendicularly away from a pivot axis to form an acute angle between said ends and a spring band in communication with each spring end to limit spring expansion.
A push-up exercise apparatus, comprising:
- a. a base to support said push-up apparatus upon an underlying static surface;
- b. a rigid member coupled to said base;
- and
- c. a first and a second hand exerciser coupled to said rigid member, each hand exerciser having a pair of elongated fingers, a torsion spring pivotally connected between said fingers, said fingers separately integral to the respective ends of said spring, and a spring band connected between said fingers to limit spring expansion;
- whereby said rigid member is no more than two feet above a support surface.
