Abdominal exercise machine
DCFirst 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. an abdominal exercise machine 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. an exertion-reducing knee carriage for reducing the effect of gravity on the user'"'"'s abdominal muscles during an abdominal exercise, the carriage being attached to the first swing-arm and the second swing-arm such that the second swing-arm is positioned in front of the first swing arm and 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. a knee supporting carriage for reducing the effect of gravity on the user'"'"'s abdominal muscles during an abdominal exercise, the carriage being 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; and c. an upper body support attached to the frame to support an upper body in front of and above the carriage oriented to stabilize and hold still the location and angle of the elbows. - 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. using the carriage to support the user'"'"'s legs and reduce the effect of gravity on the user'"'"'s abdominal muscles during an abdominal exercise; c. leaning the user'"'"'s upper body forward onto an upper body support; d. immobilizing the location and angle of the user'"'"'s elbows and upper body with the upper body support; and e. using an abdominal muscle to swing the carriage in a back and forth motion through an arcuate path behind, under and in front of the user'"'"'s waist, thereby exercising the abdominal muscle group. - View Dependent Claims (17, 18, 19, 20)
