Dinamic sports

In the past few months I started climbing, I've never been much of an athletic guy but I'm really digging it. With a recent energy boost (probably due to my current streak, longest one since I was a kid) I'm thinking of branching out towards other dinamic activities.

I was thinking about starting parkour (in a gym of course) or a fighting class (with the added benefit of being somewhat able to protect myself).

If any of you fapstronaut practices any of these activities or other you feel are alike in some way I'd love your thoughts on the sport and why you'd suggest that in particular.
