If any of them decide they might want to give any of the three sessions a day a miss, then they'll be hit in the pocket.
Speaking on BBC Radio 5Live on Thursday evening, Norwood revealed that there is a 'hefty' fine in place for any player who skips part of the programme.
He said: “We were sent back home with programmes, heart-rate monitors, watt bikes, treadmills and basically we have to check-in three times a day.
"All the stuff is recorded on your mobile, you set it all up, it goes straight to the fitness coach and if you don't do a session, it's a fine. So everybody's doing it at the moment.
"I don't know how long that continues, but we are only three days in, so you know what it's going to be like, 10-15 days time, the lads will have had enough of the sight of four walls, whether they'll carry on or not, I don't know.
"It's quite a hefty fine so you are probably better off doing it to be honest."
He added: "When they put fines on it, you have to do it, you have no choice!"
