#5 Richie McCaw
Rugby fans cannot believe Richie McCaw’s body transformation as the All Blacks legend showed off he has lost muscle mass since hanging up his boots.
Since retiring, the double World Cup-winner 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 87kg since dropping the weight.
For context, that’s a weight drop of over three stone.
