I feel like this is a stupid question (and yes, there are stupid questions), but I gotta know. I'm between gyms so recently I've been working out with a buddy in the shared gym in his apartment building. The gym has a couple benches and a lot of dumbbells as well as some machines. I've been primarily using the dumbbells (I'm old fashioned). Something is irking me though. One of the machines is a Cybex multistation. It has one function which imitates the bench press. It is plate loaded. The user lays down on a bench, grabs the handles, and does the bench press motion. Here's where things get weird: there is no indication anywhere of how heavy the plates are. There are 12 of them (plates). Toward the end it gets a bit heavy but not that heavy (I can do it on the heaviest without trouble and I'm *not* a strong guy). Is there any way to determine how heavy the plates are (without disassembling the machine and weighing them!). Thanks. Edit: I believ the machine is the "Cybex MG500." Ive found references to 230lb stacks, but i have toruble beleiving i could do that so easily. I know machiens make it easier than freeweights,, but that much?
