The Sea Eagles are five weeks into yet another punishing pre-season in the northern beaches, with sweltering conditions making training all the more draining.
But its that merciless toil and grind three months out from the season kick off that has Lui relishing the struggles of pre-season training.
Since making his NRL debut in 2010, a series of knee and hip injuries has disrupted the 23-year-olds development, but an optimistic Lui is hopeful he has seen the end of his injury woes.
The work load is a little bit more constant throughout the day and I think thats pretty good for me. Ive had a lot of injuries with my knees and ankles and I think this type of training is good for me, Lui said.
Lui played 32 NRL games in three seasons at the Broncos and is hopeful of cementing his position in the side, with the departure of several veteran forwards opening the door for new and fledgling players like Lui.
Everyones got their chance here but Ill be pushing extra hard for that. It took me a long time (eight weeks) to make up my mind whether to come here or not so I'll be pushing hard for that reason, Lui said.
The opportunity Manly gave me to come down here and be apart of a top-four front row, I couldnt go past that.
Ive been with the Broncos for eight years and it was pretty emotional for me to leave but it was a decision I had to make.
