#4 Sheamus
As a member of the WWE roster, there are few things Sheamus hasn't done. Debuting on the main roster a decade ago, Sheamus has held the WWE, World Heavyweight, United States, RAW, and SmackDown Tag Team Titles, and is just one of three men to win the Royal Rumble, King of the Ring and Money in the Bank.
Though his future in-ring career remains in question, one thing that fans have never questioned is the Irishman's incredible physique, which viewers can see him hone on his very own YouTube channel. Called Celtic Warrior Workouts, Sheamus gives a glimpse into his life as a WWE Superstar but often doesn't do this alone.
One of the best things about the channel is that Sheamus often works out with a fellow WWE Superstar, and has been exercising with Becky Lynch, Daniel Bryan, Cesaro and even his old foe John Cena. It's clear that Sheamus takes excellent care of his body, as he realizes it's the most important thing in his work as a WWE Superstar, and though it may be a while before fans see him in the ring again, we can expect him to be in great shape.
