An exercise apparatus has an exercise station that is selectively moved by
a user and has first and second weight stacks that provide selected
resistance to movement of the exercise station. The exercise apparatus
includes: (A) a frame; (B) an exercise station; (C) a first weight stack;
(D) a second weight stack; and (E) a coupling system configured to
selectively couple: (i) the first weight stack; and (ii) the second
weight stack to the exercise station such that movement of the exercise
station requires movement of at least one plate from each of: (i) the
first weight stack; and (ii) the second weight stack. A coupling member
couples the first weight stack to the second weight stack.
