I have a phobia of the pullup bar coming lose and me falling on my back. I attached it to the joists in the ceiling with lag screws. You could support a piano with it :-)

Hah maybe I am scared of the wrong thing then.

Unfortunately I'm too short and my ceilings are too tall for a joist mounted deal. (However that does mean I can do more pullups I guess)
