Adding additional 12.5 lb weight plates to the weight stack on the Weider pro 4250 831154020 Weider Weider pro 4250


Here is a link for the owner's manual on that home gym: Weider Pro 4250 Home Gym Owner's Manual. That manual shows how to assemble the gym and add the weights to the stack.


Weider does not recommend that you add more weight plates other than the stack that was originally included with the gym.  If you have broken plates and need to replace them, then the manual should help you add those weights.


If you need more help, let us know.
