My 5.5 year old's favorite thing in the world is to roughhouse and wrestle with us. It's almost like an innate need for pressure / deep physical contact, that sounds weird but hopefully you know what I mean ha. He isn't into sports at all, though obviously hasn't tried them all yet - but any other suggestions for organized activities for a kid like this? We'd love for him to have one thing he does outside the house (once COVID is not a concern of course) as his older sister has tons of activities and he really wants to do something but doesn't know what IT is.
DS says he really wants to learn to wrestle for real (not WWE, like actual wrestling) but I can't find any groups around here for elementary aged kids.

If you had a kid who loved / needed to roughhouse all the time, what activities did they enjoy?
