Former Worcester Warriors scrum-half Andy Williams says the increased emphasis on fitness testing played a part in his retirement decision.
Wililams, 30, retired at the end of last season and has taken up a coaching role at National Two club Luctonians.
He told BBC Hereford and Worcester: "You were starting to tick boxes and it just seemed to go away from the rugby.
"Even for myself who was a lover of training the continual testing became a bit too much - for me, anyway."
Williams, who helped Worcester win promotion back to the Premiership last season, believes his experience in dealing with coaches will stand him in good stead for when he now has to deal with players at Mortimer Park.
"It's nice to be on the other side and I have told the boys that as long as they are enjoying it here then we will get the best out of them," he said.
"I am as honest as they come as a person and I expect the players to be the same with me.
"It is the side of the game I have got to get used to and you have got to be ruthless, and I am, but I will always give a player a genuine reason why they are not selected.
"I know the feeling when you are on that side as that is all you want as a player - honesty."
Williams says he will encourage the Luctonians squad to play an expansive game whenever possible.
"It is the style I enjoyed myself as a player so if it's on, it's on - let's get the boys playing," he said.
"Fortunately we have got a very good forwards pack so the style will be to get them playing a bit more."
