An exercise machine having infinite range limiting capability comprises: a
frame; a pivotable exercise arm mounted to the frame configured to engage
an exercising user and moveable along a stroke path having a fully
extended position and a fully flexed position; a movement-resisting
system for resisting movement of the exercise arm along the stroke path;
an interconnecting unit for interconnecting the exercise arm and the
movement-resisting unit so that movement of the exercise arm causes a
portion of the movement-resisting unit to move in response thereto; and a
range-limiting unit for limiting the distance the exercise arm moves
along the stroke path during exercise. The range-limiting unit is
connected to the interconnecting unit and is configured to enable a user
of the exercise machine to select a first partially flexed position at
any desired location along the stroke path such that the exercise arm
moves between the first partially flexed position and the fully extended
position serving during exercise. The range limiting unit is also
configured so that movement of the exercise arm away from the fully
extended position past the first partially flexed position by the user
selects a second partially flexed position such that the exercise arm
moves between the second partially flexed position and the fully extended
position during exercise.
