"It is brilliant; things have worked well since I have been there - Tony lets me get on with it and points me in the right direction if needs be," he says.
"I am usually with the kids most of the day and when there is a ressie game I am usually with them; we have had good feedback from them and they work hard - the results have proven that when we have tested them and hopefully they will get the benefits in the future."
Teaching the youngsters good habits from scratch is one thing, but has there been resistance to a change in methods from the older, wizened pros?
Not so, says Alex, who explains:
"To be fair to them the older pros have dug straight into it and got used to things, adapting well, and have got tuned in to the way we are trying to make things go with good work ethics, hard training, and a bit of knowledge to go with it.
"We wouldn't just tell them to run round the pitch, we would tell them why they need to do it.
"The players have worked hard and you can see they are not dying off in games; results are the most important thing but fitness-wise they are retaining that."
Alex is confident promotion can be achieved this season and he adds:
"We would obviously love to be sitting on the top of the tree but at the end of the day we have got until May and we are in a good position to strike if anyone starts dropping points.
"We are doing all right and I have no worries about the first team at all - I think they will be fine."
The players trained at the Reebok centre in Beckton on Tuesday and Alex says:
"The boys are getting ready for when the rest of them come back and we will be ready to go for the next game on Saturday.
"There are big games coming up and I know the boys are up for it and looking forward to them."
Preparations for games have changed markedly since Alex played - and that wasn't so long ago - and he explains:
"With the right training and the right methods it will help them to keep fit; back in the day you used to just do a bit of stretching, come off the pitch, and find out a couple of days later that you have a strain.
"That is not happening so much any more, though people will get injured because it is a contact sport, and a dynamic one where you are running and twisting and turning.
"Accidents happen, that is life, and we can't prevent that - we just do the best we can, the players take it on board, and they reap the benefit."
