I was looking at the door gym pull up bar, as I really don't have anywhere to permanently mount a bar (at least that my wife will let me anyway :wink: ).
How secure/stable are they? Also it looks like they put a lot of weight on the door trim. My door trim is made out of some cheapo wafer board stuff held on with small nails, it is definitely not going to hold my 210lbs. Is that full weight supposed to be held by the trim, or is there some other leverage action going on?
