Here is a video about Nico Rosberg's training and what a training ! He is a formula one pilot and he explains all he does during his training with his coach and without him. I never saw such exercises as these. He does some reflex game with a ball then he stands in a push up position to resolve a memory game, then a goes back to the reflex game. He has a weird machine looking like a formula one's cockpit but there are some weight to strengthen his neck's muscles and his arm's muscle. He has to work hard on his balance and a lot of other things I let you discover in this video. This is really interesting.
