ESPN The Magazine just released their Sixth Annual Body Issue, and some of sports' biggest stars are stripping down for the popular edition.
Olympic gold medalist Michael Phelps shows off his tan-lined booty in the new issue, alongside 22 other athletes.
Wimbledon champ Venus Williams, Seattle Seahawks running back Marshawn Lynch, Texas Rangers first baseman Prince Fielder, Olympic gold-medal winning snowboarder Jamie Anderson and Oklahoma City Thunder forward Serge Ibaka are some of the other athletes who show off their fit figures in the mag.
The popular edition started out just five years ago with the mission to celebrate "the athletic form." And every year, ESPN hand-picks some of the world's most elite athletes to pose fully naked.
