WATCH: Rob Gronkowski and His Four Brothers Break Into The Running Man Challenge Dance in the Middle of a Workout

Watch the Gronk Brothers bust into the Running Man Challenge in the middle of a set in the weight room.

Rob Gronkowski and his four brothers were grinding out a workout in front of the STACK cameras today and decided to break into the ever-popular Running Man Challenge Dance mid-workout. Check out the video above to determine which Gronk bro is the best dancer in the crew.

Rob, Chris, Dan, Glenn and Gordie, Jr. should probably stick to the weight room and football field, where they generally kick ass. The Gronk Fitness plyo box in the video may have had the best moves.
