An exercise machine for performing lat pull down exercises has a main frame having a user support pivot mount, a user support pivotally mounted on the user support pivot mount for supporting a user in a seated position, and an exercise arm having handles for gripping by a user movably mounted on the frame for movement between a start position located above the head of a user in a seated position on the user support and an end position lower than the start position and generally below the user's chin. A connecting linkage connects movement of the exercise arm to movement of the user support. A load resists movement of at least one of the moving parts of the machine. The combined motion of the user support frame and exercise arm substantially replicates the natural movement of the human body when performing a free bar chin up exercise.

The machine as claimed in claim 7, wherein the main frame has a base and the pivot mount is mounted on the base. 15. The machine as claimed in claim 7, wherein the user support pivot mount comprises a four bar linkage. 16. The machine as claimed in claim 7, wherein the user engagement device is movably mounted on the main frame. 17. The machine as claimed in claim 7, wherein the user engagement device comprises at least one rigid exercise arm. 18. The machine as claimed in claim 7, wherein the user engagement device comprises a pair of independently movable exercise arms. 19. The machine as claimed in claim 7, wherein the connecting link is a rigid link. 20. The machine as claimed in claim 19, wherein the connecting link has a first end pivoted to said user engagement device and a second end pivoted to said user support frame. 21. The machine as claimed in claim 7, including a slide member slidably mounted on said user support frame, the connecting link having an end pivoted to said slide member. 22. The machine as claimed in claim 1, wherein the load comprises a selectorized weight stack. 23. The machine as claimed in claim 7, wherein the load is linked to said user support frame. 24. The machine as claimed in claim 1, wherein the load is linked to said user engagement device. 25. The machine as claimed in claim 1, wherein the main frame has an upright strut spaced forward of said pivot mount and having an upper end, the user engaging device comprising an exercise arm pivotally mounted on said upper end of said upright strut and having a first portion extending from said exercise arm pivot towards the forward end of said frame and a second portion extending towards the rear end of said frame, and user engaging handles depending downwardly from said second portion above said user support frame for engagement by a user. 26.
