CLINT Gutherson could be the fittest man in the NRL.

Prior to a season-ending ACL, the Parramatta star was blowing his teammates and opposition off the park.

He was covering so much ground at fullback that his GPS readings resembled that of an AFL player.

Having tweaked his diet and recorded the fastest times for the Eels’ pre-season fitness sessions for two years straight, Gutherson told foxsports.com.au he’s also been helping his teammates improve their fitness in any way he can.

“I like to look at it as I’m one of the best in fitness and if the boys can look to me if they’re struggling and I’m there, I can push them,” Gutherson said.

“It not only helps me but the team. I like to lead. I’ve helped a few people out, not that I’m the king of diets, but I’ve shown them what (former NRL player) Kayne (Lawton) has shown me and that’s helped them out.”

But then again, it could be Cameron Smith.

At 34, the Melbourne skipper averages 35 tackles per game and even more in Origin.

He defends in the middle for 80 minutes with the hardened edge to inspire those around him and attacks with the brilliance of a nippy teen, without ever looking like he’s fatiguing.

While there’s no streamline testing to pit every player from every club head-to-head, we’ve collected information from each team in the competition to reveal the best performers from your club.

BRONCOS

Fittest: Andrew McCullough. The hooker dominates the club’s version of the beep test.

Strongest: Joe Ofahengaue. The 112kg forward regularly bench presses 175kg and squats 215+kg.

Fastest: James Roberts. The Broncos do speed testing over 40 metres and the 23 year-old is a clear winner.

RAIDERS

Fittest: Scott Sorensen. “Scott’s all round fitness and his grit and determination in training makes him on of the clubs all round fittest player,” head of physical performance Nigel Ashley-Jones said. “He’s got a great work ethic and he’s a naturally fit player as well.”

Strongest: On raw numbers, Shannon Boyd is the strongest in the gym when doing squats and bench press. Luke Bateman and Josh Hodgson are the club’s strongest players pound for pound.

Fastest: Jordan Rapana is the quickest over 10 metres recording times of around 1.55 seconds over 10 metres. The Raiders only test speed over a short distance, so they can focus on a player’s speed off the mark and acceleration.

BULLDOGS

Fittest: Josh Jackson. “Fitness is the ability to endure long periods of optimal activity with very little depletion in effort,” Bulldogs manager of athletic performance Don Singe said.

“Josh Jackson has the ability to repeat extreme efforts while recharging on the run. As he excels in all areas of our physical performance program he takes the title of fittest all-round player.”

SHARKS

Fittest: Sharks physical performance manager, Andrew Gray, said if looking at fitness and strength across all the categories, it would be Jayden Brailey: “If you’re looking at general fitness his aerobic fitness and his strength to weight ratio puts him at the top.”

Fastest: Josh Addo-Carr. While he and fellow winger Suliasi Vunivalu are neck and neck on the feet, it’s the former Tiger who has clocked the quickest time.

KNIGHTS

Fittest: Nick Meaney won the club’s 2km time trial. Current fullback Nathan Ross finished 10 seconds slower than Meaney to claim second place. In terms of general fitness, Sam Stone and Jack Cogger are rated highly.

“Both are young, extremely motivated and committed to improving themselves physically,”

Newcastle’s physical performance manager, Tony Ayoub said. “They have made great gains this year in all facets from a strength and conditioning perspective. We all look forward to the next few years in their development.”

He then carried this form into the season.”

Fastest: James Tedesco. “James Tedesco up to 40m is the quickest at the Wests Tigers,” Kain said.

DRAGONS

Strongest: Tyson Frizell bench presses 170kg, while Leeson Ah Mau dead lifts 220kg.

Fastest: Jai Field. The Dragons do sprint testing over 30 and 40 metres and Field won both tests.

ROOSTERS

Fastest: Blake Ferguson clocked a time of 4.82 seconds over 40 metres.

WARRIORS

Fittest: “In relation to running-based fitness Shaun Johnson and Roger Tuivasa-Sheck would be the leaders at training and in game,” Balin Cupples, head of athletic performance, said. “As far as game physicality and workload go, you can’t go past Simon Mannering with his workrate both in attack and defence.”

Strongest: Bunty Afoa, 21, owns the bench press. He can push 1.7 times his body weight - a weight of almost 200kg.

Fastest: Roger Tuivasa-Sheck and Shaun Johnson have the fastest times over 30 metres.
