How do you warm up?

I've been asked several times already how the right warm up for climbing or bouldering should look like. It's individual I'd say. But these requests brought the idea to my mind to forward this question to professional athletes all over the world. So I started to interview some climbers about their warm up routine during the World Cup season, and others also sent some video footage to me. Big thanks to all of you!
