1. An abdominal exercise machine to work a user'"'"'s abdominal and oblique muscle groups and to isolate an upper and lower abdominal muscle group in a biometrically neutral position, the abdominal exercise machine comprising:
- a. a frame;
b. at least one arcuate track attached to the frame, the at least one arcuate track comprising a radius of curvature, wherein the radius of curvature is approximately 12 inches to approximately 72 inches;
c. an upper body support that supports a user'"'"'s upper body, wherein the upper body support is mounted on the frame; and
d. a sled that supports a user'"'"'s knees or legs and slides along the at least one arcuate track to exercise the user'"'"'s abdominal and oblique muscle groups.

Abstract
The abdominal exerciser of the present invention is an exercise device designed to work the abdominal and oblique muscle groups. The abdominal exerciser includes a carriage that can slide or roll along a track and an upper body support. The abdominal exerciser device is designed to simulate an abdominal exercise “crunch” motion when the knees are brought within proximity of the upper body support.

11. A method to exercise a user'"'"'s abdominal and oblique muscle groups in a biometrically neutral position, the method comprising the steps of:
-
a. fixing the location and orientation of a user'"'"'s upper body on an upper body support of an abdominal exercise machine during the exercise; b. supporting a user'"'"'s knees or legs on a sled that slides along a curved path that comprises a radius of curvature of approximately 12 inches to approximately 72 inches, wherein the user'"'"'s abdominal and oblique muscle groups are exercised; and c. pulling the user'"'"'s knees or legs and the sled towards the upper body support by contracting the abdominal and oblique muscle groups. - View Dependent Claims (12, 13, 14, 15, 16)

17. An abdominal exercise machine to work an abdominal and oblique muscle group of a user and to 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 mounted on the frame that fixes the location and orientation of a user'"'"'s upper body during an exercise; c. a carriage that supports a user'"'"'s legs or knees; d. a means for moving the carriage through an arcuate path such that a forward movement along the arcuate path allows a user'"'"'s back to exercise the user'"'"'s abdominal muscles while reducing discomfort in the user'"'"'s back, and wherein the arcuate path has a radius of curvature of approximately 6 inches to approximately 70 inches. - View Dependent Claims (18, 19, 20)
