Sergio Perez says this year's new cars are not as physically demanding as many had predicted they would be.
With increased downforce and speeds, this year's heavier cars – up from a minimum weight of 702kgs to 728 – were expected to be difficult to drive.
Many predicted that they would be physically demanding, which resulted in all the drivers upping their pre-season exercise programmes.
Perez, though, says the physicality of the cars has been "somewhat exaggerated."
"I noticed almost no difference in the physical demands between the 2016 and 2017 cars," the Force India driver told Spanish daily Marca.
"I think this point has been somewhat exaggerated."
But despite that Perez has been working hard in the gym to bulk up for the new season.
This, though, is proving a problem for Force India with reports suggesting that the VJM10 is 10kgs overweight.
As such Force India have asked both Perez and Esteban Ocon to drop a few kilograms before the season gets underway in Melbourne.
His personal trainer Xavi Martos revealed: "Checo is one of the most natural drivers on the grid and will have no problem with his neck, even if he loses kilos."
