All Blacks icon Richie McCaw looks completely different a decade after hanging up his boots

McCaw is a legendary former All Blacks captain and one of rugby's greatest players. Born on 31 December 1980 in New Zealand, he earned 148 caps and led his country to back-to-back Rugby World Cup victories in 2011 and 2015.

Known for his unmatched work ethic and leadership, McCaw revolutionised the openside flanker role. Since retiring, he's focused on aviation, charity work, and outdoor adventures, remaining an enduring icon of the sport.

Since his retirement after the 2015 World Cup win, McCaw has been passionately pursuing ultra-hardcore marathons, and the weight loss has given him a competitive edge.

The retired athlete, who previously weighed 110kg, is now around 90kg after shedding the extra pounds.

Below, we look at five other rugby stars who transformed their bodies to get themselves into top condition.

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.

Vickery is a former English rugby union player, known for his powerful scrummaging and leadership on the field. He earned 73 caps for England and was a key figure in their 2003 Rugby World Cup victory.

He wrote on Instagram: "So an idea over two years ago to be in the best shape of my life to celebrate 20 years on from winning the rugby World Cup… it’s been an interesting journey full of highs and lows but have loved the process but more importantly the people who have helped along the way @chrisbradley.uk for lighting the the flame and always being there for me.. @propowell_2001 you are the most wonderful person not just for putting the plan together but being there consistently as a friend and mentor.. but to everyone at @wsf.uk for the friendship and positive energy.. the @severnsidegym crew for the smiles and thumbs up at 5 o’clock in the morning doing cardio in the freezing cold … and couldn’t forget about mr happy @adbarnes00  .. friend’s family and my awesome team @ragingbullclothing & @no3restaurants thank you … @stillmovingmedia legends as always….have an idea get a plan and follow it through team ..

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.
