The England midfielder has an interrupted campaign last time due to an ongoing ankle problem but has been superb this season and Rodgers puts it down to some improved work by the backroom and medical staff.
"Players like Steven Gerrard have played the most amount of games they ever have consecutively," he said.
"His performance level, alongside a lot of the others, has been outstanding this year and that gives me great hope.
"We looked at every player. First and foremost it was about getting the commitment, it wasn't about motivation from the players.
"What we promised them was, once they were committed to what we were trying to do, there would be a plan put in place for the individual in order for him to play at their maximum.
"Steven has benefited from that. We revamped our medical and sports science team here and a lot of the work goes on behind the scenes.
"Our head of performance Glen Driscoll is in tune with how I work on the field, which allows him to develop the plan along with our sports science and medical team off the field.
"It is just a case of not throwing the blanket around every single one and seeing them as the same. They are very much a team but you have to look at the individual."
