Abstract
Abstract An abdominal/back exerciser is disclosed. The exerciser includes a frame having spaced side members and a seat attached to the frame between the side members. Foot braces extend between the side members on each side of the seat. A generally U-shaped lever assembly includes parallel side legs and a padded torso-engaging member interconnecting the side legs. The side legs are pivotally connected to the side members at a pivot axis intermediate their length. Weights are mounted at the distal end of each side leg. A stop mechanism limits the downward movement of the side legs to a start position wherein the torso-engaging member is elevated above the seat, whereby a user seated on the seat can lean against the torso-engaging member and rotate the lever assembly to raise the weights thereby exercising his abdominal muscles when facing the torso-engaging member or exercising his lower back muscles when seated with his back to the torso-engaging member.

Claim 1
Independent Claim
201 words
An abdominal/back exerciser comprising: a frame having spaced side members; a seat attached to said frame between said frame side members; foot bracing means between said frame side members on each side of said seat; a generally U-shaped lever assembly having parallel side legs pivoted intermediate their length to said frame side members about a pivot axis, and a padded torso-engaging member interconnecting said side legs; weight mounting means at the distal end of each of said side legs for mounting selected weights; and stop means extending laterally between said side legs of said lever assembly and said side members of said frame for limiting downward movement of said side legs to a start position, said torso-engaging member being elevated above said seat in said start position so that a user seated on said seat facing said torso-engaging member may exercise the user's abdominal muscles by leaning forwardly against said torso-engaging member to rotate said lever assembly and raise said weight and so that a user seated on said seat with the user's back to said torso-engaging member may exercise the user's lower back muscles by leaning backwardly against said torso-engaging member to rotate said lever assembly and raise said weight.
