Former England captain and flanker Chris Robshaw has dropped almost 12kg after returning from the sport last year.
Robshaw, who is now 36 years old, started playing for the national team in 2009 and amassed a total of 66 international caps.
He spent the majority of his career at Harlequins, where he played from 2005 to 2020, and concluded his playing days in the United States with the San Diego Legion.
IFollowing his exclusion from the 2011 World Cup team, Robshaw made a comeback to the England squad in 2012 as the captain for the Six Nations campaign, but injuries took a toll on him.
He's slimmed down dramatically since retiring, dropping from 112kg to close to 100kg as he continues to train for the 2023 London marathon.
Robshaw completed the run in 3:51.48.
He said: "I am pretty nervous about running the marathon, but I’ve always wanted to take part and hopefully complete one.
"I am running for my and my wife’s charity, the Kerslake Robshaw Foundation. Through the charity, we aim to empower young lives through music and sport – something very close to our hearts.
"It is completely different to rugby training. With rugby, we wanted a good cardiovascular base but it was still all about strength and anaerobic fitness – so short bursts of high intensity.
"I think I will need to lose a little more mass before I get to 23 April."
Amazing body transformations of 6 rugby stars
These rugby players have enjoyed a remarkable body transformation over the years, with some bulking up while others seriously slimmed down.
RICHIE MCCAW
The All Blacks legendary captain has revealed he's dropped 17kg since retiring, shifting what he called 'unnecessary rugby muscle'.
Since hanging up his boots following their 2015 World Cup triumph, McCaw has become obsessed with ultra-hardcore marathons and has shifted a lot of that weight to give him a speed advantage.
The 41-year-old, who weighed 107 kg, is now closer to 90kg since dropping the weight.
DAVID POCOCK
The Wallabies legend started out as an skinny 78kg teen who worked day in and day out to transform himself, with his size and strength came at a cost, Pocock told Australian Story.
PHIL VICKERY
The World Cup-winning prop has transformed his body since hanging up his boots. Vickery, who won the 2011 series of Celebrity Masterchef, has recently opened his new Cheltenham restaurant, No.3, after the Coronavirus pandemic delayed first orders. He's literally half the man he used to be.
MATT DUNNING
When he was a prop for the Wallabies Matt Dunning weighed 130kg and was constantly mocked for his tubby frame.
But since retiring from rugby union the 35-year-old has lost a staggering 40kg, dropping from 25 per cent body fat to just 11 per cent in six months.
He looks amazing.
LUTHER BURRELL
The centre missed out on Eddie Jones’ first squad for the Six Nations Grand Slam triumph in 2016 with the Aussie labelling him “grossly overweight”.
He revealed his incredible body transformation online yesterday saying in the caption…
‘Putting a picture up like this for me was very challenging and potentially very embarrassing. It can sometimes put you in a vulnerable position…. So I seriously can’t thank everyone enough for contacting me, showing interest in my continued journey and also being kind I’m still smashing through messages, so please bare with me if I haven’t yet got back to you. •’
JONATHAN DAVIES
Less Guinness and more hard work has seen the former Wales star transform himself during lockdown. He looks incredible!
