Patent ID: 7591773

Claim:
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 having a first arm portion having a handlebar proximate one end and adapted for manual operation by said user, and a 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.
