Abdominal exercise machine

摘要

An abdominal exercise machine for providing crunch-type exercises for upper and lower abdominal muscles comprises a support frame assembly and a back support member. The support frame assembly comprises a U-shaped right frame member and a left frame member which allow a user to perform various crunch type abdominal workouts. An upper right resistance band and an upper left resistance band get stretched when the user pulls an upper crossbar in a downward direction to create a weighted resistance that enables the user to achieve intense upper abdominal crunch workouts. A lower right resistance band and a lower left resistance band get stretched when the user lifts a right and a left feet inserted into a right and a left foot holding means respectively thereby creating the weighted resistance that enables the user to achieve intense lower abdominal crunch workouts.
