Are the any casual, recreational sports that it would be possible to join?

I've never been one for sports–I was always a marching band kinda guy–but I've seen posts on here, and on various discords here and there, where people have organized casual games of volleyball or kickball that people are able to join. I'd love to do something like that, but I haven't seen a post mentioning them in a while, and I'm not sure where I would go about finding out about them–if they're still around at all. Is anyone organizing anything like that that I could learn more about? Furthermore, do any gyms or anything already have things like this that I could look further into? Thanks!!
