Double Unders

Advanced Level of Difficulty

The double under is an advanced conditioning exercise that requires the athlete to perform two revolutions of the skipping rope for every single jump.

Calves (calf muscles) influence the ankles and contribute to overall ankle strength. Strengthening your calf muscles will help your balance and performing movements such as running, walking and jumping.

The quadriceps (quads) are a group of four muscles on the front of the thigh. They allow your knee to straighten and provide stability when standing. Your quads are the most important muscle group for maintaining the ability to stand and to walk independently.

Skipping Rope

Skipping rope is a low impact, aerobic exercise. In contrast to running, jumping rope is unlikely to lead to knee damage since the impact of each jump or step is absorbed by the balls of both feet rather than the heels which greatly decreases the ground reaction forces through the patella-femoral joint.
