I have a nutritionist and a doctor. Everything is checked. Thoroughly. Everything I take is checked out first.

I'm an all-around fighter. I do everything. I've got wrestling; I've got Brazilian jiu-jitsu, and I've got striking.

This level of competition is extremely high. Everybody is trained. Everybody has a game plan. Everybody has a nutritionist. Everybody has everything. It's here that you realize, as people, we're all equal.

I have stated many times that one of my goals was to become K-1 champion. K-1 is, in our country Holland, very popular, and it's a big opportunity to become the first person that holds two world titles in two different sports.

I'm just cruising, doing me, having a good time and focusing on getting better.

As a fighter, you need to constantly improve. So that's what we've been doing: constantly improving striking, grappling, wrestling - there's always different aspects to improve.
