Olympic swimmer Michael Phelps is the fittest man alive, according to Men's Health magazine.

The most successful Olympic athlete in history with 22 medals, 27-year-old Phelps was named the magazine's number one fittest man of all time, beating Bruce Lee, Arnold Schwarzenegger and Muhammad Ali.

James Bond actor Daniel Craig also made the cut, coming in at number 50.

The Daily Mail reports Men's Health as saying: "His portrayal was fitter, meaner, angrier, and darker than any Bond in the history of the franchise - and that's why Craig's Bond is also one of the best".

"He looks like the kind of Bond you could imagine a henchman legitimately running from - cobblestone abs, monster traps, and hardly an ounce of fat anywhere.

"In other words, he's the Bond who finally made kicking ass in a tuxedo believable again".

Others included in the list are Sylvester Stallone, Lance Armstrong, David Beckham and actor Gerard Butler.
