Abstract
An exercise apparatus has a support frame and a seat mounted on the support frame having a forward end. A leg exercise arm has a first end pivoted to the support frame adjacent the forward end of the seat, and a second end. The arm has a continuous curve extending along at least a major portion of its length and bending through an arc of at least 180 degrees. In its rest position, the arm first projects forwards from the pivot and then bends back rearwards. A cable links the arm to an exercise resistance, and a leg engaging assembly is mattached to the arm for engagement by the legs of a user in performing exercises.
Claims18
An apparatus for performing exercises, comprising:
- a support frame;
- a seat mounted on the support frame and having a forward end;
- a unitary, one-piece exercise arm having a first end pivoted to the support frame adjacent the forward end of the seat, and a second end, the arm having a continuous curve extending along at least a major portion of its length and bending through an arc of at least 180 degrees, the arm having a rest position in which the continuous curve of the arm first projects forwards from the pivot and then curves back rearwards up to the second end of the arm located rearwardly of the pivoted end;
- a cable linking the arm to the exercise resistance;
- and
- a leg engaging assembly attached to the arm for engagement by the legs of a user in performing exercises.
