I want to use a framed doorway to do chinups but I'd hate to come crashing down to the floor on my tail bone. This doorway is framed but not drywalled.
I realize there are a lot of factors but not sure how to calculate this. The stamp on the 2x4 says "A. F. P. A. 134 S-P-F xxxx KD-HT 2" where xxxx is illegible. I don't know what any of that means but maybe it's useful.
I weigh about 210 lbs.
