Abdominal exercise machine
First Claim
1. An abdominal exercise machine to work an abdominal and oblique muscle group and to isolate an upper and lower abdominal muscle in a biometrically neutral position, the abdominal exercise machine comprising:
- a. a frame;
b. an upper body support to provide support for a user;
c. a first swing-arm pivotally connected to the frame;
d. a second swing-arm pivotally connected to the frame; and
e. a carriage attached to the first swing-arm and the second swing-arm such that the second swing-arm is non-parallel to the first swing-arm, thereby allowing the carriage to swing back and forth in an arcuate path parallel to a plane defined by the frame.

Abstract
An exercise device designed to work the abdominal and oblique muscle groups. The abdominal exerciser comprises a carriage connected to a frame by a swing-arm that allows the carriage to swing along an arcuate path. In some embodiments, the carriage is connected to the frame by non-parallel first and second swing-arms. The carriage is adjustable so as to accommodate users of different sizes and to isolate different abdominal muscle groups. The abdominal exerciser device is designed to simulate an abdominal exercise “crunch” motion when the knees are brought within proximity of an upper body support.

8. An abdominal exercise machine to work an abdominal muscle group and isolate an upper and lower abdominal muscle group in a biometrically neutral position, the abdominal exercise machine comprising:
-
a. a frame;
b. an upper body support to support an upper body;
c. a carriage connected to the frame by a swing-arm, wherein the swing-arm is pivotally connected to the frame and connected to the carriage, thereby allowing the carriage to swing back and forth in an arcuate path parallel to a plane defined by the frame. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of exercising an abdominal muscle group of a user in a biometrically neutral position, comprising:
-
a. placing at least a portion of a user'"'"'s legs on a carriage;
b. immobilizing an upper body by leaning forward on an upper body support; and
c. using an abdominal muscle to swing the carriage in a back and forth motion, thereby exercising the abdominal muscle group. - View Dependent Claims (17, 18, 19, 20)

21. A method of exercising an abdominal and oblique muscle group in a biometrically neutral position, comprising:
-
a. pulling a user'"'"'s knees along a longitudinal arcuate path towards a user'"'"'s chin thereby performing a contraction of a user'"'"'s abdominal muscles such that pulling the user'"'"'s knees along the longitudinal arcuate path allows movement of a back to follow a natural curvature of the back;
b. moving the user'"'"'s knees along the longitudinal arcuate path away from the user'"'"'s chin thereby allowing the user'"'"'s abdominal muscles to relax; and
c. repeating the pulling and moving steps in order to exercise the user'"'"'s abdominal muscles. - View Dependent Claims (22, 23, 24)
