Abdominal muscle training apparatus
First Claim
1. Exercise apparatus comprising:
- a support frame including a pair of cross linked parallel tubular members and having a base member;
a seat portion associated with said base member, said seat portion comprising a buttock support element and a knee rest element and being thereby adapted to support a user in a half-kneeling position; and
a lever frame including a pair of cross linked parallel tubular members and havinga first arm portion having a handlebar proximate one end and adapted for manual operation by said user, anda second arm portion arranged generally perpendicular to said first arm thereby to form a generally L-shaped lever frame, said second arm terminating at a flee end and being linked to the base member via a pivot;
said second arm inserted between said parallel tubular members of said support frame base,and wherein said first and second arms are joined at a rounded junction at or adjacent a fulcrum for the lever flame, such that counterclockwise rotation of the lever frame about the fulcrum causes clockwise rotation of the support frame about the pivot, and vice versa;
and wherein said junction is arranged to bear directly or indirectly against a working surface beneath the exercise apparatus;
whereby in use, the exercise apparatus is operable by said user manually pushing repeating a cycle of applying manual force to said first arm so as to push said first arm away from said user'"'"'s body, and subsequently releasing said applied force thereby to rotate the lever frame about said fulcrum, thus lifting said second arm, which in turn causes the seat portion associated with the base member to lift and tilt, the user'"'"'s abdominal muscles thereby being exercised in lifting the user'"'"'s own body mass.

Abstract
Exercise apparatus (10) for training the abdominal muscles of a user (41) comprises a lever frame (11) linked to a support frame (12) at a pivot (13). The lever frame (11) has first and second arms (14, 15) joined at a central junction (16) which also forms a fulcrum for the lever frame (11). The support frame (12) consists of a base member (19) having a seat portion (21) associated therewith. The apparatus (10) is adapted to support a user (41) in a half-kneeling position so as to promote neutral pelvic alignment during the performance of abdominal muscle training exercise. In use, the exercise apparatus (10) is operated by the user (41) pushing the first arm (14) away from his or her body so as to cause the lever frame (11) to rotate about its fulcrum (16). This lifts the second arm (15), which in turn causes the seat portion (21) associated with the base member (19) to lift and/or tilt. The user'"'"'s abdominal muscles are thus exercised in lifting his or her own body mass.
