A father of three, King, was happy to reveal the secret to his success - crossfit training.
"Crossfit is great for pre-season training. It teaches you to push yourself when you are stuffed. Last year I was 122kg and now I'm down to 113. The aim is to get down to 100kg before I fight in the Battle for Life," he said, referring to his boxing debut on September 21.
"I'm quite surprised at how fit I am. This is definitely the fittest I've been since I played for the Hawke's Bay Unicorns rugby league side back in 2003."
He used to work in the bush which kept him fit but an accident several years ago saw him switch to a "sit down" job, unloading logs for DG Glenn Logging at Panpac.
"It's not physical ... all buttons and steering wheels so that's why crossfit is so important to me.
"It was while doing crossfit I meet up with some blokes from NOBM who asked me to come and play for them," King said.
The former Phoenix, Seals and Pirates club rugby league player is enjoying his season and is confident NOBM can beat MAC at Flaxmere's Ron Giorgi Park on Saturday in a match likely to decide who qualifies second for the semifinals.
"We were rubbished a bit in the papers at the start of the season. But we've built each week and got better and better."
Should NOBM pip MAC on Saturday like they did in their Nash Cup clash (15-10) it will be no surprise if King and his fellow tighties are among the first the NOBM supporters raise a glass to. The battle of the two packs should be a beauty.
An interesting aside to the match is the fact the MAC head coach, Pat Benson, is also a life member of the NOBM club.
