The Warriors did a lot of pre-season fitness work heading into their 2018 NRL campaign, and for good reason.
The running game looks likely to be a big part of their plan this year, with Blake Green's addition in the halves allowing Shaun Johnson to play his instinctive, off-the-cuff brand of football.
And when Johnson is running, the backs have to try keep up.
Winger David Fusitu'a, who scored two tries in the side's opening round win against South Sydney, said the team had to be ready to run this year.
"As soon as Shaun gets through that first line of defence you've just got to get on your bike and try to catch him and hopefully just give him some options," Fusitu'a said.
