I have a Weider Platinum exercise machine that I've never used because of having constant surgeries in my my back and neck since 1/5/2000. I'm finally at a stage in my health that I can begin to use this machine but I can't figure out, for the life of me, how to arrange and rearrange the cables and pulleys for each exercise. Is there anything available that shows all the steps necessary that I'm looking for. Please help.
