In CrossFit, double unders are everywhere — from benchmark workouts to the CrossFit Games. If you can't string together consistent double unders, you're leaving time on the board. This guide covers the progression from single bounces to unbroken sets of double unders.
Efficient double unders can save you minutes on workouts like Annie, Double Grace, and any WOD with jump rope movements.
Practicing jump rope when tired builds the coordination you need to hit double unders in the middle of a grueling WOD.
Jump rope teaches you to maintain steady breathing rhythm — a skill that directly transfers to pacing in CrossFit metcons.
Single unders at an easy pace work great as active recovery between heavy lifting days.
Get to 100 unbroken single unders before attempting double unders. You need consistent bounce height and rope speed.
Slap your thighs twice per jump without a rope. When you can do this consistently, add the rope for double unders.
Engage your core and jump straight up and down. Piking (kicking feet forward) is the most common double under fault.
Heavier ropes are easier to learn with, but a lightweight speed rope is essential for fast double under sets in WODs.
