Cristiano Ronaldo may be hot, but according to a new survey the Real Madrid star is not the fittest athlete in sports. That honor goes to Lebron James.

According to Sports Illustrated magazine's new Fittest 50 survey, James is king. The survey was based on four criteria: strength, speed, endurance and agility.

James was number one, while Ronaldo came in at number two. Usain Bolt, Floyd Mayweather and Dez Bryant rounded out the top five. Ronaldo recently said he didn't work out just to get his abs in shape, but for strength reasons. "I don't do special exercise to get a six-pack," the soccer player told Men's Health this month (via E! Online). "I train to be strong for the whole season."

"To be the best you can be, you have to be focused," Ronaldo said. "Training your mind is very important. Then distractions are no longer distractions. You can remain calm if you are confident. The harder you work and the more committed you are, the more confident you become."

Ronaldo is currently overcoming an injury and didn't play in the "friendly" match Real Madrid just had in the United States in July. "Tomorrow I will be better than today, and next year will be better than this one. If I score 50 goals, I want 55. Some people say I'm too serious on the pitch, not smiling and so on. It is because I'm focused 100 percent on every game. I always want more and more."
