In Crossfit gyms and competitions, athletes often use thin wire cable ropes. These ropes eliminate any resistance or feedback in the rope, which would otherwise slow down the rope and force the jumper to work harder for the same output. In competition, their goal is to breeze through their sets of double unders as fast as possible. So, the tool they choose is specifically designed for this goal.

For those who are new to Crossfit or those looking to master their double under technique specifically, the wire rope will not be the go-to rope of choice. Conditioning and building efficiency in your technique are not the same as testing your efficiency. For this purpose, a beaded rope will be the best choice. It will offer maximum resistance which will help push your technique to new heights. A 5mm PVC is a good alternative, but not as favourable as the beaded rope.

Supplementing your Crossfit workouts with dedicated double-under skill training using a beaded rope will be the sure-fire approach focusing on your fundamentals. This will build an overall better proficiency with your double unders by conditioning your wrists and elbows for the movement pattern.
