Absent this week, of course, are the likes of Dario Chistolini, Charlie Sharples and Henry Trinder who have been playing in the Churchill Cup while James Simpson-Daniel and Mike Tindall are away with England.
Meanwhile, the season still hasn't finished for our England U20s - Koree Britton, Ryan Mills and Dan Robson - who are participating in the Junior World Championship in Italy.
However, the hard work has already started and Allen confirmed that the foundation work that served Gloucester so well last season remains in place.
"We've gone for much the same blueprint again this year. We've tweaked the programme slightly and learned from a few things that we did last year in preseason to hopefully benefit the players this time around."
"We didn't really start conditioning the main group until a few weeks in and picked up a few soft tissue injuries in preseason. So, this time around, we're going to incorporate a conditioning session at the end of each week."
"We've also put in a couple of new sessions that the players aren't aware of and they're going to do the first of those this week. But I think that the programme that we've put in place will certainly stand us in good stead for the new season."
With a number of players away on World Cup duty this autumn and a smaller squad than last season, injury prevention is going to be crucial, an area Jersey born Allen was reasonably satisfied with last season.
"I was very happy. There were certain parts of the season where we were battling a little bit with injuries and international call ups but, throughout most of the year, our top end players were fit for the vast majority."
"There's a certain amount of luck in that, as there is with everything. But I also feel that the programme that we the Strength and Conditioning Coaches put in place, coupled with the work that the Medical Department did, gave the players what they needed to function to the best of their ability whilst being injury free."
"You usually find that, if guys pick up something, then they've usually got a little niggle until they can rest completely and it's obviously difficult to do that in season."
"If a player misses a week in preseason then they end up missing a huge amount of potential physical work so we want to decrease any chance of getting an injury whilst pushing the players and it can be a difficult balancing act."
While the blueprint has remained relatively the same, Barny and his team leave no stone unturned when it comes to trying to find new approaches to keep Gloucester ahead of the game and this preseason sees a new element being unleashed on the unsuspecting players!
"It's been termed athletic performance. We feel that there's been a gap between what we do in terms of strength and conditioning with our work in the gym and our speed and conditioning work and the prehab the Medical Department give to the players."
"We made a lot of progress last year with some of our landings and our thinking of bodies in motion all of those bits and pieces."
"This athletic performance is, in essence, like gymnastics. Almost going back to some of the things that players were doing or should have been doing when they were young, between five and ten years old, and learning how to use their bodies."
"We're trying to go back to that a little bit and it's going to be interesting to see how they take to it but we certainly believe in it and are hoping that it will then pay dividends as we move forward."
"A few bits will be slightly difficult and taxing for the players but, if we can stick with it and gradually progress things, then that will be good."
