Going and getting swole will still get you women but not because of your big muscles in most cases. The dedication and follow through needed for that demonstrates value. Other hobbies are the same way. Of course some women like huge muscled men or cars or d&d or guitars or whatever but the ability to be both interested in and interesting about something is more attractive than the results.

You hit the gym everyday and you'll get way more compliments from men than women. Same if you have some sweet car. It's the effort to attain that super nice back and thick heavy lats that women respond to more so than the muscles themselves in most cases.

Doing something is more interesting than doing nothing. Plenty of guys without hobbies or interests will still find mates but it's harder to get someone to want to know you and get to the point where they love your interiority without some kind of interest. Touch grass, join like minded people for activities, enjoy yourself and the rest will follow.

Tldr.
Slay orcs, cook food, ~~go into the glimmer on a military mission then return potentially infecting Natalie Portman~~ go to avenge a family member killed by the Lannisters and you too can be the middle guy (whoever that is)
