Abstract:
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.
