The Double Under requires a high level of Coordination, a rhythm. If your rope is flying about haphazardly in a desperate attempt to make your first Double, so be it. But beyond your first, you should be able to hear a pattern in the sound the rope makes.
I do not consider the Double Under to be an “Rx skill.” If you can complete a single under, you can likely complete a Double Under. Practice EVERY day.
N.B. – Emily Cuba is a superb athlete and super fun to boot. You might think that my favorite part about her would be something along the lines of her excellent development as an athlete during her time here at CrossFit 314, but in truth, my favorite part about her is that she has never once not let me call her EmCee Hammer. She just went with it.
