2. Olympic Runner: Shalane Flannagan

Distance runners who compete at such a high level require hours of training per day and very few breaks throughout the year. They must constantly pay attention to their diet, sleep well, and do everything they can to stay healthy and avoid injuries, which they are extremely prone to when putting such high stress on the body.

4. Pole Vault

Professional pole vaulters must be very flexible yet also have a lot of muscle mass. They have no fear of heights or fear of falling, even though they fall many times during practice and risk a lot of energy. When done correctly, pole vaulters can make the task of vaulting themselves several feet into the air seem effortless and graceful.

5. Baseball

Baseball players require a different type of fitness than many other athletes; they more upper body strength, yet they also need the speed to round the bases quickly and very quick reflexes. In this picture, 2011 World Series MVP David Freese celebrates while running around the bases after hitting the game-winning home run of World Series Game 6.
