The exercise device includes a first portion and at least one of a first extension hingedly coupled to a first end of the first portion and a second extension hingedly coupled to a second opposite end of the first portion, each of the first and second extensions including a flat bottom wall, a top surface, a pair of opposing side walls, and a resilient material extending between the bottom wall and the top surface.

Description

BACKGROUND OF THE INVENTION

The field of the invention relates generally to exercise equipment, and more specifically, to apparatus and methods of strengthening the abdominal muscles and the lower back muscles.

Many exercise positions and motions used to strengthen muscles are performed such that the muscle or muscle group of which the muscle is a part are isolated when performing the exercise. For example, when strengthening the muscles of the abdomen or lower back, sit-ups, crunches and leg lifts may be performed from a supine position.

For comfort and isolation of the muscles, an assistance device may be used. At least one such device is described in U.S. Pat. No. 5,611,765 to Frederick Koch, which describes an exercise device which exercises the abdominal muscles over their full range of motion, which makes the abdominal muscles work fully, and which exercises the lower abdominal muscle and the lower back muscles as well as the upper abdominal muscles.

However, such devices may not extend sufficiently to provide adequate cushioning of the body during the exercise or may be difficult to maintain in place during the exercise. There is a need for additional support and cushioning for the user during exercise periods using abdominal and back muscle conditioning equipment.

BRIEF DESCRIPTION OF THE INVENTION

In one embodiment, an exercise device for exercising the upper and the lower abdominal muscles and the lower back of a user includes a first portion that includes a flat bottom wall, a pair of opposing side walls, a central section having a generally flat top surface, the plane of the top surface being generally parallel to the plane of the bottom wall, a first end section attached to a first end of the central section, the first end section having a top surface inclined with respect to the bottom wall at a first angle, and a second end section attached to a second opposing end of the central section, the second end section having a top surface inclined with respect to the bottom wall at a second angle. The exercise device also includes at least one of a first extension hingedly coupled to a first end of the first portion and a second extension hingedly coupled to a second opposite end of the first portion, each of the first and second extensions including a flat bottom wall, a top surface, a pair of opposing side walls, and a resilient material extending between the bottom wall and the top surface.

In another embodiment, a method of forming an exercise device includes forming a first portion having a planar bottom surface and an arcuate cross-section, the arcuate cross-section having a first height at an apex of the arc, the first portion formed of a resilient material and forming a first extension hingedly coupled to a first edge of the first portion, the first extension having a planar bottom surface co-planar with the bottom surface of the first portion, the first extension formed of a resilient material.

In still another embodiment, an exercise device includes a first portion including a flat bottom wall, a pair of opposing side walls, a central section having an arcuate upper surface, the plane of the top surface being generally parallel to the plane of the bottom wall, and at least one of a first extension hingedly coupled to a first end of the first portion and a second extension hingedly coupled to a second opposite end of the first portion. Each of the first and second extensions including a flat bottom wall coplanar with the flat bottom wall of the first portion when fully extended, a top surface, a pair of opposing side walls, and a resilient material extending between the bottom wall and the top surface.
