One of the best athletes on the tour, Johnson is also one of the fittest. The 6’4" giant squeezes every bit of power out of his large frame. In 2015 so far, Johnson leads all PGA players with an average driving distance of 317.6 yds. When Johnson hits a ball well, he can drive it over 400 yards. One training method Johnson attributes to his success is explosive medicine ball training. With a medicine ball in his hand, Johnson emulates his swing, exploding and whipping the medicine ball when his hands reach the place where he would connect with the golf ball, according to Golf Digest.
Then again, another reason why he's so fit might have something to do with his wife, model Paulina Gretzky—yes, Gretzky, as in daughter of The Great One. We're guessing she knows a little something about physical fitness, too.
