Chiefs boss Dave Rennie hailed the work of his backroom staff after his side's impressive dismantling of the Brumbies on Saturday.
The 2012 and 2013 champions were in imperious form away in Canberra, running in six tries in a huge 48-23 victory.
Despite a recent travel schedule that has taken them to South Africa and Argentina, before heading to Australia, the Chiefs looked fresh and Rennie credited the strength and conditioning members of his coaching team for getting the side into excellent shape.
"I think our support play and our ability to keep the ball alive's been massive, and a lot of that comes down to our conditioning as well," Rennie told Stuff.
"I think Phil Healey, our trainer, and his team have done an amazing job.
"We are a very fit side. We have been pretty clinical in those last parts to storm home. We're really happy with the attitude and the work ethic."
Leading the Australasian Group after six rounds, the Chiefs are now set to welcome back a number of fresh legs in the shape of locks Brodie Retallick and Dominic Bird, along with scrum-half Tawera Kerr-Barlow and hooker Nathan Harris, ahead of their clash with the Blues.
"It'll be nice to get some fresh legs back in the mix," Rennie added.
"It's such a tough competition, you can get rolled by anyone at any time. We've been pretty clinical over the last couple of weeks and we've been rewarded for that, but you get carried away with that at your peril.
"They're always massive clashes Blues-Chiefs, and they've got someone in their camp [Tanerau Latimer] who's played a fair few games for the Chiefs so knows a bit about us.
"We've got to make sure that we prepare really well and that we're up for the game on Friday, so there won't be any talk about our bye this week."
