Pull up bar is not something I can't install in my apartment as landlord won't approve. I am only renting so can't do many modifications here. I would love to have that option.
The door frame pull up bars are non-permanent, and can work in many cases. At most you might have to paint a bit.
If you're in a city there has to a playground nearby providing all sorts of options.
I think people just get too tied to a gym, when there are countless options to get really good workouts if the gym is unavailable for a period of time.
