Do any of you cross-train or participate in any sports or activities, that are not combat related, that you believe contributes to your martial art training?

I know most sports and such will help in general fitness, but aside from that anything more specific.

Like;

I snowboard, wakeboard and ride motocross. All three of these really give my adductor muscles a work out.

I also work in construction, and swinging a hammer is a very good workout for stickfighting.
