Bryce Harper pulls 550 pounds to get ready for upcoming season

Washington Nationals slugger Bryce Harper is one of the strongest athletes on the planet. It's easy to tell this when he's blasting home runs, and we've known that Harper is a strong guy ever since he was first introduced to the world a few years ago as a high schooler.

Yet here's some more evidence: Harper pulling 550 pounds about 30 yards. Bonus points for putting the camera on top of the plates.

Harper hit 13 home runs in 2014, averaging a "true distance" of 397.8 feet, according to ESPN Stats & Information Group. His farthest home run came in Safeco Field against the Seattle Mariners on Aug. 31, when he sent a Hisashi Iwakuma pitch out of the park by a true distance of 418 feet.

We'll see if the weightlifting has any bearing on raising those numbers in 2015.
