Henderson has admitted he can't help himself from doing that little bit extra, but now he takes advice from the Kop coaches to take it easy and it's paying dividends.
Henderson said: "Sometimes I need people to tell me to rest.
"After training sometimes I like to do a little bit extra.
"A few of us do a bit of shooting or whatever it might be but sometimes you need to give your legs a rest and prepare for the game in the best way that you can.
"We have the right people at the club to tell you when you can and when you can't do the extra bit."
