As the new Championship season edges ever nearer, fitness regimes are becoming more intense and the Royals are set for more match practice over the weekend in Holland.
John Swift is well aware of what is expected at this important time of year, though, and he says he is expecting a tough schedule as the squad regains fitness.
Having had a shorter break than most following the Under-21 European Championships with England, Swift got straight back into the Royals' regime as he arrived in Holland at the start of the week.
Speaking on the role of the club's sport scientists and backroom staff, he said: "You've got to trust them, you have to know what they're good at, and they've done it all of last season and it's all paid off.
"They all do their job and hopefully we can get better as players.
"You've got to put in the work, every player knows that as well. When you go out and train it's obviously quite hard, but you can't hide. It's all on the computer afterwards, so you've got to put in the work."
Swift believes the current Royals squad push each other on to new heights in training with the analysis of data, with competition among the squad to achieve the best results.
He says this pays dividends on the pitch, though, with the players' physical condition allowing them to improve as footballers.
"Training can be a slower session but I think everyone really wants to do well," he explained.
"Everyone wants to improve so that can make an easier session a bit harder than normal, because everyone wants to do well.
"I think that's a good thing, all the lads want to get better and if every session is like that, then I'm sure we will."
The Royals continue their pre-season schedule on Saturday with a double header in Oosterbeek, taking on Dutch top tier side Sparta Rotterdam and Belgian outfit Cercle Brugge.
