We all know F1 drivers have to be supremely fit, but just what are the particular challenges unique to driving cars at over 150mph?

In the latest Sky Sports F1 podcast, one of the most familiar faces in the paddock, Kimi Raikkonen’s long-time trainer Mark Arnall, chats to Martin Brundle about life as a fitness trainer in F1.
