I'm just not somebody who can sit around doing nothing, and all of us in the Foo Fighters have our own things outside of the band. I'm not going to use the cliche that those outlets bring us back fresh and with new ideas, but what I will say is that it keeps us all feeling free - and that creative freedom is a very positive thing.
I trained in martial arts and wanted to become a UFC fighter. That was my goal. I only really learned how to dance three weeks prior to making 'Step Up Revolution.' Dancing will always be fun, but MMA is something I'll never give up. I will eventually get back in the octagon and be fighting professionally again.
