Reading's Kitson unhappy with training methods
The 27-year-striker is the first to admit his training methods are unusual for a professional footballer.
Now sport scientist Kunle Odetoyinbo, who recently joined from Wolves, faces the almost impossible task of changing Kitson's views.
But the former Cambridge United hitman is ready to dig in his heels, saying: "After four days off I don't like going straight into it.
"Others players can but I like to build up slowly which is why these international breaks are a nightmare for me.
"Kunle has changed a lot of things. He's very enthusiastic and is working us hard but I'm probably one of the most awkward people he will meet.
"I don't like using up too much energy in training - I find it pointless."
But his comments may not impress the club's coaching staff, including boss Steve Coppell who has criticised his work ethic in the past.
However, Kitson insisted: "We're not here to impress the manager in training. He probably doesn't agree with that but, from my point of view, a player has already impressed the manager otherwise he wouldn't be here.
"He knows what we're capable of and I have always believed that if you play me I will score goals and play well for the team.
"I've been here four years now and Steve knows that and I know that. It doesn't mean I won't try but people's bodies are different and I can't go 100% flat out in training then 100% in a game for 40 weeks of the year.
"I've been trying to tell Kunle what I'm like. I think he understands but he finds it difficult to believe a Premiership footballer can't train and play. But he'll come round and get used to it, he'll learn."
