Joey van den Berg says that an intense pre-season is a necessity ahead of a relentless upcoming campaign.
The heat in Holland has meant that the Royals have had to train earlier in the morning to avoid the hottest temperatures, but preparations ahead of the new season have stepped up a gear once again in Oosterbeek.
The midfielder explained that, while he enjoyed his summer break, he is ready to get his second season as a Royal underway.
"In this stage of the pre-season, I think we need to step it up... and the lazy days are over!" Van den Berg said.
"We have to go for it. This is where you get the real profit from training, so you really need to step it up for yourself and go for it.
"It's very warm but that's why we've trained an hour earlier, it was okay because there was a bit of a breeze but it's always better than freezing!" he joked.

Last season was the midfielder's first experience of football outside his native Holland, with more league matches and a lack of a winter break adding to the challenges of playing in England.
Van den Berg says he feels better for the experience, though, quipping: "When I'm getting older, I really enjoy the break!
"It was a long season, especially for me without the winter breaks, so I really enjoyed the summer but that's over now.
"We're back on the field and it's always good to start again, pre-season is not the best part of the season but it's necessary.
"We already said it a few times but we need to step it up now and show what we're really capable of and take it to the next level.
"That takes hard work, we're going to have to suffer a bit, so we'll see how we're going to do that."
