PICTURE THIS: A gold medalist decathlete, an NFL quarterback, a 100-meter sprinter, a Grand Slam tennis champion, an NBA MVP, a world-class rower and an American Ninja Warrior walk into a room. Who is the fittest of them all?

Determining the answer seems impossible, considering the wide range of shapes of elite athletes, as well as the different demands of their sports. Physiques are carved and cut and chiseled with different goals. Take, for example, four-time Tour de France winner Chris Froome (No. 12 on the list) and Patriots wide receiver Chris Hogan (No. 36). Though they both are 6'1", Hogan is 63 pounds heavier (210) to be able to take a pounding on the football field, while Froome focuses on staying lithe and strong to pedal Alpine roads. From a boxer's ability to absorb and deliver blows, to the agile and acrobatic movements of a gymnast, fitness is measured in distinct ways from sport to sport. So how do you level the playing field?

With insight from a panel of trainers, strength-and-conditioning coaches and performance experts (left), SI set out to identify the 50 fittest men and women across all sports. Athletes were considered based on their performances over the last 12 months, the demands and risks of their respective sports, their training regimens, their longevity and other physical benchmarks including agility, flexibility, endurance, power, speed and strength.

While all athletes are committed to staying in shape, who stands head and sculpted shoulders above the competition?
