Got a question for any o the big guys who do pullthroughs: If (a) the stack only goes up to 200, (b) there's only space to add four 5lb weights on top of the stack, and (c) there isn't really the room to add a plate behind the pin securing the stack, how do you do heavier pullthroughs?
Actually ... I just got thinking: maybe there's another machine somewhere in the gym that has a heavier stack and a low cable.
