Professional athletes do their best to stay in shape to boost their performance. However, some do it better than others.

Sports Illustrated put together a list that ranked the 50 fittest athletes in sports. It rated athletes on speed, strength, agility and endurance. Each category was based on a scale of 0-10, so a perfect score would be 40.

There aren't many surprises near the top of the list.
