They can normally be seen on the rugby pitch - with their kit firmly on.
But here are rugby stars Danny Care and Ugo Monye looking very different.
The Harlequins stars didn't get their kit off for fun - they did so to raise awareness of male cancer for Everyman, the prostate and testicular cancer campaign.
Cosmopolitan magazine's Everyman centrefold campaign, which began in 2001, has seen numerous stars strip off in the name of charity including Lenny Kravitz, Danny Cipriani, Ewan McGregor, Danny Dyer and Eminem, among others.
All men who pose for the centrefolds do so to raise awareness of male cancer.
