Single Unders Review

Single Unders: General Characteristics

A single under is where you jump and spin the rope once, using a suitable jump rope. Fitness single unders are fairly simple to perform once you’ve mastered the basics and provide an effective, affordable way to add exercise to your workout regime.

Single Unders: Progression

When it comes to jumping rope as a beginner, you need to be aware of some important techniques. Follow this step-by-step guide and you’ll be doing single unders in no time.

Step 1: Practice the different elements

Before doing single unders, you need to be aware of the different elements and be able to perform them with good technique so you can put them all together.

Start by practicing the jump. With your feet hip-width apart, practice jumping up and down repeatedly on the spot. Jump using the balls of your feet, making sure your heels don’t touch the ground. Keep a little tension throughout your body so you don’t move around too much. If you’re having trouble staying still, mark the floor with an X or draw a small circle.

For the arm swing, you want them to remain stable whilst mainly using your wrists to move the rope. You want your wrists to do the work, not your arms. Try to keep your elbows stable with your hands around the height of your hips and arms at 45 degree angles.

For both the jump and wrist movements, using a metronome set at a certain speed can help you to practice keeping a constant rhythm.

Step 2: Practice your timing

Once you have a good idea of the jump and wrist technique, next you need to practice the timing of both so you’ll be able to put them together with the rope.

A good single under exercise is to place both rope handles in one hand and use your wrist movement to turn the rope to one side whilst you practice the jump. To practice timing, try to coordinate your jump and rope swing so that you come off the floor as the rope is about to hit the ground at your side.

If possible, have a friend check your timing from the side so they can let you know how you’re doing. If not, use a gym mirror.

Step 3: Start in the correct position

Once you’ve got the technique and timing for the jump and arm swing, it’s time to put them together with the rope. Grip the rope handles loosely and hold the jump rope in front of you. Keep your hands together and elbows tucked in to start.

Step 4: Practice toe catching

Once you’re in the correct position with both hands on the rope, swing the rope behind your head.

Bring the rope forwards back over your head using the correct wrist motion and arm position, but don’t jump. Try to catch the rope in your toes before lifting your heels and letting the rope go through.

Repeat this until you feel comfortable catching the rope and letting it go.

Step 5: Perform a single under

Now that you’ve mastered the different elements, practiced the timing and general movement, it’s time to perform a single under.

Start slowly and progress up, performing one single under then two etc and keep building up your number until you can perform them naturally. The key is to keep practising so your body develops muscle memory for the correct movement.

3 Tips for Single Unders

Once you’ve started to do some single unders, here are some tips to help you master them and move on to more difficult jumping skills:

1. Size your jump rope correctly

If you don’t size your rope correctly, it can make performing single unders much more challenging.

You’ll need to make sure the rope is correct for your height and arm length. Most ropes come with a brand-specific sizing guide when purchasing that you need to make sure to use.

3. Focus on maintaining your technique

Once you have the technique down and you can do a single under, the next step is making sure you can maintain the correct technique.

Losing your posture can make it harder for you to keep the same rhythm, meaning you’ll need to use more energy to perform the same movement.

If you want the rope to keep moving smoothly, make sure to keep the same wrist flick and try not to use your arms too much.

When you’re jumping up and down with a bit of tension throughout your body, try to keep the same distance between your feet and the ground every time you jump.


Why are double unders better than single?

Double unders are better than single unders for a few main reasons. They are much harder to do, requiring more coordination and conditioning. They burn more calories as you have to work harder to spin the rope around twice in a single jump and also, they look much cooler.

How can single unders be improved?

Once you’ve mastered the single under, more complicated exercises include the alternate food step, the side swing, the crossover and the double under.

Conclusion – How to Master the Single Under

Single unders are a fun and simple way to improve your fitness and general conditioning. To master the single under, follow the step-by-step process I’ve described above and make sure to choose a suitable jump rope before sizing it correctly.
