Double unders are a style of jumping rope where the rope makes two rotations between every jump. They are a staple in many CrossFit and HIIT workouts, and are often cursed as being one of the most frustrating skills to learn. I genuinely think that if you are struggling with double unders it is because you are overthinking them or focusing your practice in the wrong places. Let’s get this out of the way right now, double unders are NOT just spinning a rope twice as fast as regular jumping rope. Double unders don’t require much in the way of strength at all, instead it is all about rhythm. Learning double unders is like learning an instrument, you wouldn’t just pick up a trumpet and assume you should be able to play it immediately, right? It just requires practice. If you put in the work, you will learn them. Let’s break down Protest Fitness’ method of learning double unders.
