Double Unders

The DOUBLE UNDER is the signature intermediate-to-advanced skill: the rope passes under your feet TWICE in a single jump. It's not about jumping higher or flailing your arms — it's about a slightly higher, well-timed jump combined with a FASTER wrist turn to whip the rope around twice before you land.
