Abstract: An exercise machine with controlled motion and user force matching resistance. The machine includes a frame to which is rigidly mounted a motor driven reciprocating drive. A user engageable arm is pivotally mounted to the frame. The reciprocating drive is connected to the arm by a rigid connecting rod. The reciprocating drive drives the arm through a predetermined stroke following a pre-determined velocity profile. The user performs the exercise by applying force to the arm. The arm applies a generally equal counterforce to the force applied by the user. The pre-determined motion of the arm is generally independent of the force applied by the user. The stroke of the arm has a fixed fully contracted position and a user adjustable fully extended position. Adjustments to the fully extended position are made by changing the location of the joint between the connecting rod and the arm. Motion of the arm starts upon application of force applied by the user, and stops when the user force is removed.
