“We’re trying to coordinate the rope swing with the perfect jump,” says Buddy Lee of the CrossFit Preferred Course: Jump Rope. Lee, who is a U.S. Olympian, CrossFit jump rope subject-matter expert, and widely recognized as one of the world’s foremost jump rope authorities, leads a master class in this common CrossFit exercise. Participants will leave the class with clear paths to elusive jump rope skills, such as double-unders, triple-unders, and more.
