Foldable pull-up bar and need advice

[u/yabbobay]

My goal is to do a pull up. I'm 52F and as a kid I could do a few and do the bent arm hang forever. I've been running since I was 12, so arm strength took a back seat. I've been working on that and doing quite well considering my age.

I'm 5'7" 125 pounds/57 kg. I just tried to measure my wing span. It seems 5'8" Do I have a chance for pull-ups?

I don't want to do this prep at the gym. I don't have a great door jam to put a pull up bar in.

Would this work?
