"Me and (Stephen Kearney) catch up all the time and focus on what needs to be focused on; tick all the right boxes."
The 32-year-old has missed games in all four of his campaigns with the Warriors, including the 2019 campaign, and has been an 80-minute option in less than half of the matches he's played for the club.
Last season, Luke produced 13 performances of 80 minutes or more and looked to be getting back toward the form he showed in his time with the South Sydney Rabbitohs.
However shoulder and hamstring issues have limited his production in 2019, keeping him out of the preseason and two of the side's matches early in the season.
"I've got to take into account that I'm getting old too. That's what I put it down to," he said.
"(My body) was good the last two games, I felt quite good. When you're feeling like that you kind of don't want to stop, but we got a weekend off, now we're building to Saturday.
"I've just got to keep trying to play well and keep myself in there."
