> How do you go from talking to someone during some hobby activity to a friendship outside of that activity?

This is where having multiple hobbies not only adds depth to conversations & makes you more interesting, it allows you to cross-pollinate your friend groups from each hobby. If you join a cross fit gym and a running group (as others have mentioned in the thread), then you invite someone from the gym to the group or vice versa.

The invitation can either be a "I think you'd really enjoy this activity", in which case you're introducing them to something new and cool, or it can be "I think you'd really like the people I do X with" in which case you're helping them meet friends.

People who take you up on the offer to either try something new or meet new people with you as their guide are sure to become friends. You get to see each other in new elements and your relationship can now trascend simply doing one activity together.

I think this approach feels a lot more natural than jumping straight to "hey, I've seen you at the rock gym a bunch, let's get coffee?" which can feel like a big jump and somewhat forced.
