MONTMELÓ (Ekstra Bladet): This season’s new vægtregler means that drivers can eat and work out markedly different, before it backfires.

High drivers like Nico Hülkenberg and Romain Grosjean do not need to starve themselves, when from in years will be filled up with ballast to 80 kg; all are equal.

But also smaller drivers like Lewis Hamilton and Kevin Magnussen have packed pounds on. Many said Hamilton without wanting to clarify.

Previously there was Kevin Magnussens back at around 69 kg. Under test is the 73, and it helps him.

– Throughout the day I have said to my coach, how nice it is to feel the improvement. When I step on the scale, I can see that I have put on four kilos. And it is clear that four pounds gives the bonus, he said after Wednesday’s 131 laps.

They can still feel in the neck, but the extra muscle helps. Not least because the Danish racing driver still does not sit perfectly.

I have a problem with my neck because the headrest pushes my head too far forward. So I’m stuck in a discomfort position during braking, in which my head moves too far forward. With some changes, it is much better than last week, but it still happens.

First to Melbourne comes a whole new headrest, which should make the experience in the small cockpit more comfortable.

Romain Grosjean lifted too blurry for its weight in the last week. He has gone from 69 to 74 kg and expect to trim one of the to the start of the season.
