Cable Crunch Exercise The Guide to Building a Strong Abs

Cable crunch exercise is a great core exercise that can build your abdominal muscles, which is why they are performed by bodybuilders, strength athletes, and general gym-goers.

However, cable crunches require the use of a cable column, which can be difficult for people who do not have access to a cable machine, either because you work out at home or because the cable machines at your gym are usually busy.

You shouldn’t be able to train your abdominals if you can’t do wire crunches, therefore I’ve compiled a list of the finest substitutes.

What Is a Cable Crunch Exercise?

A Cable crunch exercise is a type of abdominal workout that allows for overloading to cause hypertrophy. It enables regulated motion and the ability to add or decrease weight with the pull of a pin by using a cable or a pulley machine for resistance. This exercise focuses and loads the rectus abdominis muscle directly. (1)

Benefits of cable crunch exercise

Crunches on a cable machine have various advantages over crunches on the floor. It offers an increase in resistance, allowing the individual to overload a muscle. (2)

Overloading puts the muscle under more strain than it is used to. As a result, the muscles adjust by synthesizing more contractile components, making the muscle stronger to withstand the extra tension. (3)

When doing crunches on cable machines, the individual can change the weight to their needs in order to gradually progress the workout. The cable also maintains continual stress on the abdominal muscles, allowing them to work throughout the range of motion.

A cable crunch, like a typical crunch, strengthens the core and targets the rectus abdominis while also engaging the obliques. The core muscles assist in the transfer of weights from the upper to lower body and vice versa. Strengthening the core muscles helps to stabilize the spine and keeps it from being overloaded.

Muscles worked by cable crunch exercise

As an isolation workout, the cable crunch is a simple ab action. Yes, your arms and traps will be required to hold and support the weight, but they should not be involved in the actual action.

Rectus Abdominis muscle

The rectus abdominis is the primary muscle recruited by the cable crunch. This is your six-pack muscle, which is located in the center of your torso. Its major function is to flex your spine, thus the Cable crunch exercise is an excellent choice for targeting this muscle group.

How to do cable crunch exercise

Cable Crunch


  • Set the proper weight on the stack and attach the rope attachment to a high pulley cable.
  • Face aside from the cable machine and stand directly in front of it.
  • Drop to your knees and grab the rope behind your head with your palms facing inward.
  • Your buttocks should be perched atop your feet. Crunch down as far as you can while keeping your elbows bent and your hands at either head or shoulder height.
  • Pause for a moment, then slowly lower yourself back to your starting position.


  • This exercise is most effective when performed slowly and in perfect form.
  • Your buttocks should always be touching your heels.
  • Instead of turning at the hips, focus on clenching the abs in.
  • As your weight increases, you may find it more comfortable to lay the rope on your shoulders.
  • Choose a weight that is not so hefty that your lower back handles the majority of the resistance.

Common mistakes of cable crunch exercise

Avoid utilizing a swinging action when doing wire crunches, even if it makes the exercise easier. Also, resist the impulse to assist with your arms by adjusting the distance of the triceps rope from your head.

A rhythmic rocking motion with your upper body can make the workout easier but less effective. Perform cable crunches in a controlled and precise manner, lowering the weight as necessary.

If you put your head straight down towards the floor, you may have a poor execution. As a result, your lower back curves more, putting undue strain on your lumbar discs. Instead, concentrate on bringing your chin to your knees. This allows you to maintain strong core tension and keep your back reasonably straight during the activity.

Always remember that practice makes perfect. You’ll be able to do cable crunches effectively and securely while targeting your abs for a stronger core if you follow these step-by-step instructions and avoid frequent blunders.

Cable Crunch Variations

Standing Cable Crunch: The standing Cable crunch exercise can increase your core strength and stability while also providing a wide range of motion. However, this also increases the difficulty of achieving maximum abdominal contraction.

Close the distance between your sternum and pelvis to accomplish the movement. Avoid worrying about bending down straight. Consider pulling your hips forward as you crunch and looking at your belt buckle to help with form.

Machine Crunch: The machine crunch can make it easier to target the abdominal muscles because the machine puts you in a good position. In this variation, you sit upright and the machine will assist in flexing your torso, with your chest and thighs meeting in the middle.

Because you may focus on feeling the abs rather than coordinating movement during the workout, this exercise variant can help you create a stronger mind-muscle connection. A stronger mind-muscle connection can lead to feeling the muscle working even harder during more demanding workouts like the cable crunch.

Cable Crunch Alternatives

Decline Bench Sit-Up

Decline Bench Sit-Up

The closest exercise alternative to the Cable crunch exercise is the decline bench sit-up due to the significant range of motion and spinal flexion needed to perform the movement. All you need is a bench set to a declined angle.

You can make the exercise more challenging by raising the angle of the bench and/or by adding resistance using a dumbbell or weight plate.

Floor Crunch

Floor Crunch

Floor crunches are the most straightforward substitute for the cable crunch. All you need is a floor to get started.

It’s simple to do and has a very small range of motion. This exercise is typically linked with lifters who are fresh to training and learning the fundamentals.

BOSU Crunch

BOSU Crunch

Because of its unstable surface, the BOSU ball is an excellent training tool for improving stability, particularly of the core muscles. Because of the shape of the ball, it also provides an additional range of motion when performing crunches and specifically targets the upper rectus abdominis muscle.

Exercises that target the abdominal muscles have long been popular because of the aesthetic definition they provide while attempting to achieve what is popularly referred to as six-pack abs.

Cable Crunch Vs. Traditional Crunch

Both cable crunches and regular crunches are popular ab exercises, but there are several important differences between them.

Cable crunches use a cable machine to provide resistance, while traditional crunches use the weight of your own body. This means that cable crunches can be made more challenging by adding more weight, while traditional crunches are limited by your own strength.

The range of motion is another distinction between the two activities. Crunches are normally performed by bending your torso forward until your chest meets your knees. Cable crunches, on the other hand, provide you a wider range of motion because you can draw the cable down as far as you can.

Is kneeling cable crunch effective?
