ELI5:. Does habitually holding in your pee for long periods of time strengthen or weaken your bladder long-term?

My guess is that it weakens it, but I would love to have an explanation either way.

For people who have stress incontinence we recommend Kegel exercises. Which is like stopping your pee in the middle of peeing. It does not strengthen the bladder but it does strengthen the surrounding muscles.
However holding your pee constantly can result in urinary tract infection. It does not really have any benefits.
