If you work on virtually anything that has been exposed to the outside, you know how hard it can be to get a nut to separate from a bolt, particularly if rust is involved.
You have a better chance of breaking the bolt, particularly if you are relying solely on your massive arm strength. (If the bolt is big enough, you also can injure yourself.)
But anyone who knows anything about working with metal and rust understands that the easiest way to separate a rusted nut or bolt from a nut or bolt is to break the rust bonds that are holding it together.
Depending on the size of your nut and bolt, there are a few hacks you can use to force that separation without landing yourself in bed for a few days to deal with a back injury (not that that has ever happened to me!)
