I am trying to find a way to add a pullup bar to my home gym. Ordinarily the pullup bar contraption goes over and through the door frame, but the door frames we have go all the way up to the ceiling so this does not work. I am looking for a way to add a 2 x 4 or something similar to the door frame in order to make this work. Obviously I have no clue how to do this. As I am a renter I do not want to cut out a piece of the door frame in order to notch the bar (or 2 x 4) in. Does anyone have any recommendations on what I should do? Note the door does not actually close so I would entertain anything up to and including the removal of the door.
I googled online and cannot find anything that gives me any ideas.
