In modern day?
I feel like Ganondorf would keep himself physically strong by having a regular training routine, but I don't think he'd be a "gymbro" per say, like making the gym his entire personality. It would just be part of his regular daily maintenance, like skin care, hair care etc.
I do think he'd be a film bro, a music bro, and an overall arts bro. I think he'd enjoy watching movies, visiting art galleries, and listening to music with a critical eye/ear, and he would have a lot of opinions on it. I think he'd be a very obnoxious arts bro when it comes to critique, and I do think he'd spend a significant amount of his time and money on pieces he particularly enjoys.
