Always gonna plug disc sports when threads like this pop up. Ultimate Frisbee is fun and if you live in even a minor city there’s usually a rec league to join. Has the best culture of any sport IMO, full of the chilliest most accepting people who are always looking for more people to join and with rec leagues people will sometimes go out to the bar after to hang out.

Disc golf is also great for meeting people if you’re not as into cardio. Can join tournaments and they’ll usually pair you up with people. Or just go solo to the course and occasionally someone else will offer to let you join their round or if you’re waiting with another solo at a hole you can offer to let them join you.

Both are also very cheap activities, Frisbee you just need cleats and to pay ~$50 for a rec league season. Disc golf is basically free once you get discs.
