Studying multiple arts?

How many of you are studying multiple arts at the same time?

Is it feasible, or would a better approach be to concentrate on one art and then switch to a different art.

Most pro fighters today seemed to have started from a single art and then added elements that were missing from their game.

Thoughts?

I think to begin with it's better to train in two at once. While you're learning new things, you can't really afford to miss a few weeks and come straight back to it, you really need it drilled in to your head.

What's your goal?

If you want to be Olympic gold medalist in wrestling or judo, just choose that sport.

If you want to be a well rounded fighter, cross-train from the beginning: takedowns, subs, striking.
