Double Unders are tricky and for some, hard to master.  But once you have the movement down they are a breeze! A Double Under is performed when the rope completes two revolutions during one jump. These are sure to make an appearance in The Open, so get practicing! 
With Double Unders sure to make an appearance in The Open, make sure you have the skill dialed in! Check out our Movement Series video and blog post about Double Unders. Posted by The FeedX on Tuesday, February 9, 2016
  Starting Position: -You should have a loose grip on the jump rope handle -Shoulders should be relaxed -Elbows should be close to your side and the rope should start behind you -You should be able to see your hands in your peripheral (so they will be slightly in front and to the side of your body) [caption id="attachment_349230" align="aligncenter" width="225"]Starting position for double unders, with a relaxed grip and close elbows.

As you start to practice double unders, just remember to stay relaxed and keep the fundamentals from single unders. -Jump SLIGHTLY higher than when performing a single under -Stay on the toes/forefoot when jumping, and point the toes down towards the ground (power jump) -Keep the shoulders relaxed -Spin the rope using the wrists, NOT the shoulders -Keep your gaze neutral (try to find a point across the room and fix your gaze there) [caption id="attachment_349234" align="aligncenter" width="300"]The jump during the double under.
