Why do Formula 1 racing drivers need to be fit? Sky News sports journalist Ian Dovaston learns the hard way as Lewis Hamilton's personal trainer puts him through the paces.

Ian did a great job of playing up to the camera and I loved working with the very beautifully shot Mclaren Formula 1 footage. Obviously none of the slo-mo picture had any audio. I am therefore particularly pleased at how well the fake "slo-mo audio" works that I cobbled together from various sources on the last shot. The graphics sequence in the middle was made by the Sky News graphics department.
