Double unders rank as one of the most demanding and gratifying skills in CrossFit. They not only deliver a vigorous cardiovascular workout but also demand a blend of coordination, timing, and consistent practice. Whether you find it challenging to maintain more than a few consecutive jumps or you’re eager to enhance your double-under proficiency, this guide is designed to help you advance. 

Here’s a list of 10 frequent double under mistakes and tips on how to correct them.

Incorrect Rope Length

  • Mistake: Using a jump rope that is too long or too short can affect timing and efficiency.
  • Fix: Stand on the middle of the rope and pull the handles upward; they should reach just under your armpits. Adjust accordingly.

NOT Owning a jump rope

  • Mistake: Using a different rope every time
  • Fix: Invest in your own jump rope to ensure consistent practice with the same jump rope each time. Many people make the mistake of simply using any rope available at the gym. This often results in using a rope that differs from their previous one and likely isn’t properly sized for them. Even minor variations in the rope can disrupt your timing. By consistently using the same rope, your body and mind can more rapidly adapt to the mechanics of the movement.

Poor Arm Positioning and not enough wrist

  • Mistake: Arms held too wide or too high waste energy and make it hard to control the rope.
  • Fix: Keep your elbows tucked in and close to your body at all times and use your wrists to swing the rope, not your arms. It’s All About the Wrists( remember that) it’s up to the wrists to make the rope pass under your legs twice while you jump. Practice rotating your wrists without the rope to get a feel for it. 

Excessive Jumping Height

  • Mistake: Jumping too high leads to wasted energy and slower rope speed. You’ll wear your legs out too quickly jumping high.
  • Fix: Keep your jumps low (about 1-2 inches off the ground), just high enough for the rope to pass twice.

Inconsistent Pacing

  • Mistake: Alternating between fast and slow jumps can throw off rhythm.
  • Fix: Maintain a consistent, moderate speed. Use a metronome app if needed to develop a steady rhythm.

Looking Down

  • Mistake: Staring at the ground can throw off your balance and posture.
  • Fix: Look straight ahead to maintain balance and proper posture.

Using Too Much Force

  • Mistake: Overpowering the rope swing can lead to loss of control.
  • Fix: Use light flicks of the wrist to maintain control over the rope’s speed and position.

Poor Timing

  • Mistake: Initiating the jump too early or too late in relation to the rope swing.
  • Fix: Practice the timing without the rope, focusing on the rhythm of the swing and jump.

Tangled Rope

  • Mistake: Not using a smooth-surfaced rope or using a worn-out rope, which can snag or tangle.
  • Fix: Use a high-quality, smooth rope and replace it regularly to avoid inconsistencies caused by wear.

Inadequate Warm-Up

  • Mistake: Jumping into double unders without sufficient preparation can lead to poor performance and injury. Warming up properly is essential for performing double unders effectively and avoiding injury. 
  • Fix: Here are some key warm-up exercises that can prepare your body for this high-intensity skill:
  1. Jump Rope Singles: Start with basic single jumps to get your blood flowing and your rhythm going. Aim for a smooth, consistent pace.
  2. Light Cardio: Spend a few minutes doing light cardio like jogging, high knees, or jumping jacks. This gets your heart rate up and muscles warmed up.
  3. Leg Swings: Do forward and side leg swings to loosen up your hip flexors, hamstrings, and glutes. This increases your range of motion and prepares your legs for the explosive movement needed for double unders.
  4. Wrist Circles: Since double unders require significant wrist action, it’s good to warm up your wrists. Make gentle circles in both directions to reduce the risk of strain.
  5. Calf Raises: Strengthen and warm up your calves by doing calf raises. This helps prevent cramping and facilitates the quick, springy jumps needed for double unders.

Lack of Core Engagement

  • Mistake: Not engaging the core, which helps stabilize the entire body during the exercise.
  • Fix: Actively engage your core muscles throughout the exercise to improve stability and power.


Mastering double unders is not just about practicing the jumps; it’s about correcting small mistakes that can lead to big improvements. By focusing on these tips, you can enhance your technique, efficiency, and performance in double unders, turning this challenging skill into a powerful asset in your fitness regimen. Put in the practice and the effort, and you’ll be a double under pro in no time.
