AvatarByJeff Duncan Crossfit

Crossfit has taken the fitness world by storm with its intense and dynamic workouts. But if you’re new to this popular fitness regime, you may be wondering what exactly are double unders in Crossfit? Beyond being just an impressive-looking movement, double unders are a staple in many Crossfit workouts for good reason. In this article, we’ll dive into the ins and outs of double unders and why they should be a part of your Crossfit training. So grab your jump rope and let’s jump right in!

What Are Double Unders?

Double unders are a common movement in the sport of CrossFit. It involves swinging a jump rope twice under your feet per jump, resulting in passing the rope under your feet twice before landing again. This creates a double rotation of the rope and requires speed, coordination, and timing. Although it may seem simple at first glance, mastering double unders takes practice and skill.

The Benefits of Double Unders

Double unders provide numerous benefits for athletes in CrossFit. One of the main advantages is improving cardiovascular endurance. The speed and intensity needed to perform double unders require a high level of aerobic capacity, which translates to improved overall stamina.

Another benefit is developing coordination and balance. Double unders require synchronization between your upper body and lower body, along with proper footwork and timing. Practicing this movement can increase body awareness and improve overall balance, making you more efficient in other CrossFit exercises.

In addition to physical benefits, double unders also offer mental benefits. Performing continuous repetitions of this challenging movement can build mental toughness and help you push through fatigue during intense training or competitions.

Tips for Mastering Double Unders

Here are some useful tips to help you master double unders:

1. Start with single jumps: Before attempting double unders, make sure you have mastered single jumps first. It’s essential to have good form and rhythm with single jumps before moving on to more advanced variations.

2. Use an appropriate rope length: The length of your jump rope is crucial for successfully performing double unders. If the rope is too long or too short, it can affect your timing and cause frustration. A general rule of thumb is to adjust the rope so that the handles reach just below your armpits.

3. Focus on timing: The key to mastering double unders is proper timing. It would be best if you timed your jumps to coincide with the rope passing under your feet twice. It may take some practice, but once you get the timing down, it will become second nature.

4. Keep your arms close to your sides: It’s essential to keep your arms tight and close to your sides when performing double unders. This helps maintain control of the rope and prevents excessive swinging, which can throw off your timing.

5. Relax and stay calm: It’s common for beginners to become frustrated when trying to master double unders. Remember to relax and stay calm; tense muscles can hinder coordination.

Variations of Double Unders

There are several variations of double unders that you can incorporate into your CrossFit training:

1. Single-single-double: One of the most straightforward variations is performing single jumps followed by a double under repetitively. This allows you to build endurance while still practicing the movement.

2. Triple unders: A more advanced version is performing triple rotations with the jump rope instead of two. This requires even more speed and coordination than a regular double under.

3. Cross-arm double unders: In this variation, you cross your arms in front of you while swinging the rope twice per jump. This not only challenges coordination but also strengthens core muscles.

Common Mistakes When Performing Double Unders

Here are some common mistakes beginners make when attempting double unders:

1. Using the wrong rope length: As mentioned earlier, using an incorrect rope length can hinder performance and make mastering double unders more challenging.

2. Jumping too high: Some athletes try to maximize their jump height when performing double unders, thinking it will make it easier for them to pass the rope under their feet twice. However, this can lead to extra fatigue and make it harder to maintain proper form.

3. Having tense shoulders or arms: Tension in your upper body can disrupt coordination and hinder timing. It’s essential to stay relaxed and keep your arms close to your sides.

4. Rushing the movement: Trying to perform double unders too quickly can cause mistakes and hinder progress. It’s crucial to practice proper form and timing before increasing speed.

In Conclusion

Double unders are a staple movement in CrossFit that offers numerous benefits and challenges. With the right technique, practice, and patience, you can master this movement and take your fitness to the next level. Don’t get discouraged if it takes time; like any skill, it takes dedication and determination to master double unders. Remember to start with the basics and gradually work your way up to more advanced variations for optimal results.

Double unders are a staple in Crossfit training that can be both intimidating and rewarding. This challenging exercise involves jumping rope while rotating the rope twice under your feet with every jump. Double unders require coordination, agility, speed, and endurance, making it a true test of an athlete’s fitness level.

The Benefits of Double Unders in Crossfit

Double unders are more than just a fancy skill to show off at the gym. They offer numerous benefits that contribute to overall physical fitness. The following are some of the main benefits of double unders in Crossfit:

1. Improved Cardiovascular Endurance

Crossfit is known for its high-intensity workouts that push athletes to their limits. Double unders are no exception to this, as they require constant movement and sufficient oxygen supply to sustain the exercise. This leads to improved cardiovascular endurance, allowing you to perform longer and more intense workouts without getting tired easily.

2. Increased Speed and Agility

The faster you rotate the rope during double unders, the more reps you can complete in a given time. This not only improves your speed but also challenges your agility as you need to have quick reflexes to keep up with the pace of the rope.

3. Enhanced Coordination

Double unders require perfect coordination between your arms and legs as well as precise timing. This results in improved neuromuscular coordination, which is crucial for many sports and daily activities.

4. Builds Strength in Lower Body Muscles

The repetitive jumping motion in double unders primarily targets your calf muscles, quadriceps, hamstrings, glutes, and core muscles for stability. Over time, this builds strength in these muscles and improves balance, making you more efficient in other physical activities.

5. Quick WOD Finisher

Crossfit workouts are designed to be intense and time-efficient. Adding double unders as a finisher to your WOD (workout of the day) is an excellent way to challenge your body and get a great workout in a short period.

How to Do Double Unders

Now that we’ve covered the benefits let’s get into the nitty-gritty of how to do double unders in Crossfit.

1. Master Basic Jump Rope Technique

Before attempting double unders, you need to have a good grasp of the basic jump rope technique. This involves keeping your elbows close to your body, wrists rotated slightly outward, and jumping off the balls of your feet.

2. Start Slowly

It’s essential to start slowly and focus on perfecting your form as you progress towards double unders. Begin with single jumps and gradually increase the speed until you can do at least 100 repetitions without breaking form.

3. Get the Timing Right

The key to double unders is timing. For every jump, you need to rotate the rope twice before landing back on the ground. It’s essential to put in enough effort for each rotation rather than trying to save energy by doing small jumps.

4. Keep Your Arms Relaxed

Tensing up your arms can make it harder for you to move quickly and efficiently while rotating the rope. Keep your arms relaxed and let them guide the rope without using too much force.

5. Practice Consistently

Double unders require practice, practice, and more practice! Don’t get discouraged if you can’t nail them right away – keep practicing regularly, and over time you will see improvement.

Tips for Mastering Double Unders in Crossfit

Now that you know how to do double unders, here are some tips to help you master them in no time:

1. Invest in a Good Jump Rope

A high-quality jump rope can make a significant difference when it comes to double unders. Look for a rope that is the right length for your height and has comfortable handles that provide a good grip.

2. Focus on Breathing

Just like any other high-intensity exercise, breathing is crucial during double unders. Proper breathing technique will ensure adequate oxygen supply to your muscles and help you maintain your pace.

3. Keep Your Core Engaged

A strong and stable core is essential to performing double unders correctly. Keep your core engaged throughout the entire exercise, which will also help protect your lower back from injury.

4. Use Mental Visualization Techniques

Mental visualization is a powerful tool for mastering any new skill, including double unders. Before attempting the exercise, visualize yourself successfully completing multiple repetitions, which can help calm your nerves and improve overall performance.
