Red Bull Racing driver Max Verstappen looked quite the picture as he hit the gym this week.
The 20-year-old was on the ski slopes over the Christmas and New year holidays. But there's only so much preparation you can do for Formula 1 while on the piste.
So this week it was back to the off-season 'office', and some proper work in the gym. In particular, it's the neck muscles that require a lot of work to maintain while away from the race track.
You can see Verstappen using a weight-loaded strap around his head to simulate the G-forces that drivers experience during a Grand Prix.
Even the fittest drivers can struggle to keep their heads up during some of the longest, fastest races on the Formula 1 calendar. The sooner they start getting their neck muscles into shape for 2018 the better.
The first test of the new 2018 cars takes place at the Circuit de Catalunya-Barcelona on February 26 - March 1. It's followed by a second pre-season test at the same venue a week later. The first race of the season is the Australian Grand Prix in Melbourne on March 25.
Meanwhile, top marks to Verstappen's photographer for selecting a mean and moody monochrome effect for the picture!
