Yeah, man. Dudeism is compatible with athletics. After all, the Dude allegedly bowled (though there is no photographic evidence) and he clearly dabbled in Tai Chi. Me? I'm an old broken-down man, but I started (no gi) jiu-jitsu about 18 months ago. I think it's dudely. You simply can't think about work, life, problems, or other shit when someone is trying to take you down, choke you out, or twist off an arm/leg. It gets you out of your own head - which, to me, is a good part of what I get from Dudeism, in general, too.
