The trio all played together at Leeds United and are working hard to get fit ahead of pre-season.
Norris, who left Leeds in 2015, is a qualified personal trainer and he was putting some of his former Elland Road teammates through their paces this afternoon.
Norris played with both Wootton and Murphy for three seasons at Leeds, and they have remained in contact.
Wootton is currently without a club, following the shock news that his contract with the Whites had expired at the end of last season.
It was originally thought that Wootton was under contract at Leeds until 2017, but that turned out not to be the case, and the Yorkshire side decided to allow the former Manchester United man to leave.
Murphy is the only one of the aforementioned trio to remain at Leeds.
The central-midfielder is likely to have an important role with the Whites next season, with Garry Monk in charge.
Leeds are still yet to confirm their pre-season schedule for next term, with only a handful of friendly matches arranged.
