Milner, 34, has played 34 times this season in winning this third Premier League title after two previous successes at Manchester City.
He is sure he can make an impact next season too - and has the data to prove it.
"I think coming out of lockdown I managed to put 10 centimetres on my jumps so that's not too bad at my age. I'll take that," he says.
"The fitness test is interesting coming back every pre-season and seeing where you are at. I reassess all the time definitely, I try and push as hard as I can
"I've taken up Yoga a lot of people have had good things with that so I started that the last four or five months. We are very well looked after with support from physios, sports science and nutritionist, things like that.
"You can't go on forever but hopefully I can drop off from being the front of the running to the middle of the pack rather than the middle of the pack to the back.
"I feel pretty good to be fair. There's the odd day you get out of bed and feel a bit stiff but I'm sure that's the case for most of the lads. I just want to go as long as I can."
