Hmm... Should I get into dumb VR games like BeatSaber? I want to do something that feels like intense fighting. Biking fast enough it's satisfying is too dangerous. Maybe unrealistic point based karate would be fun. I tried fencing once but it was shockingly lame. I'd join a dodgeball league but there aren't any, everyone wants to do like baseball and volleyball. Hmmmm. I wonder if paintball would be fun or tedious, I could see it going either way.
Oh yeah some spicy lead climbing can cause a flow state similar to what I'm looking for, with the increased adrenaline and body awareness. But instead of slow careful movements I want fast instinctive ones.
I forgot to mention racquetball as an example of the feeling. Probably the best thing I've found so far actually, and it's safe, but I'm not in college anymore :(
Guessing you've searched for squash courts? I only just learned racquetball and squash are "the same" (I'm guessing there's differences.)
