The double jump rope, often called the double under, is a high-intensity bodyweight cardio drill where the rope passes under your feet twice on a single jump. It is a conditioning movement that taxes your cardiovascular system while loading your calves and lower legs, with your shoulders and forearms working to spin the rope fast. It is a staple for building footwork, coordination, and explosive endurance.
How to do the Double Jump Rope
- 1Hold the rope handles at hip height with your elbows tucked close to your sides and your forearms turned slightly outward.
- 2Stand tall with your feet together, knees soft, and your weight balanced on the balls of your feet.
- 3Begin a steady single-bounce rhythm to find your timing before attempting the double pass.
- 4Jump a little higher than a normal skip, driving through the balls of your feet while keeping your torso upright.
- 5Spin the rope faster using quick wrist rotations so it passes beneath your feet twice during that single jump.
- 6Land softly on the balls of your feet with your knees slightly bent to absorb the impact.
- 7Reset your rhythm and repeat for the planned reps or time, keeping the rope turning at a constant pace.
- 8Slow the rope back to single bounces to finish, then stop and let your breathing settle.
Form tips
- Drive the rope with small, fast wrist circles rather than swinging from your shoulders, which keeps your rotation efficient and your forearms fresh.
- Keep your jumps low and compact; you only need a few extra inches of height, not a high leap, to fit two passes.
- Stay on the balls of your feet and land softly to protect your calves, lower legs, and joints from repeated impact.
- Build up gradually by alternating one double under with several single bounces until your timing and conditioning improve.
- Choose a non-slip surface and warm up your calves and ankles first, since the fast pace is demanding on the lower legs.
Common mistakes
- Swinging the rope from the shoulders instead of the wrists, which slows the rotation and tires your shoulders and forearms too quickly to complete two passes.
- Piking or kicking the heels back to buy time in the air, which wastes energy and throws off your landing and rhythm.
- Jumping far too high to force the double pass, which spikes impact on your calves and lower legs and burns you out fast.
- Landing flat-footed or with locked knees, which increases joint stress and makes it hard to rebound into the next jump.
- Looking down at your feet, which rounds your posture and disrupts the upright balance the movement needs.
Frequently asked questions
What muscles does the double jump rope work?
It is primarily a cardio conditioning drill rather than a muscle-building lift. The repeated bounding works your calves and lower legs, while your shoulders and forearms turn the rope; the main benefit is cardiovascular endurance and coordination.
Is the double jump rope good for beginners?
It is an advanced skip that demands solid single-rope timing and conditioning first. Beginners should master a steady single bounce, then practice one double under at a time before stringing reps together.
How high do I need to jump for a double under?
Only a few inches higher than a normal skip. The extra air comes from spinning the rope faster with your wrists, not from leaping high, so keep your jumps low and compact.
How many double unders should I do?
As a cardio drill, work in sets or timed intervals — for example 3 to 5 rounds of 20 to 30 reps, or 30 to 60 seconds of effort with rest between. Adjust to your conditioning and keep your form clean.
What is a good alternative to the double jump rope?
Single jumps with the rope build the same footwork and cardio base at a lower intensity. They are the natural progression step and a solid substitute when you want the conditioning without the faster rope speed.
