The cable machine is a real gem in the gym, known for its versatility and user-friendliness. It's a go-to for many exercises targeting the chest, back, shoulders, and arms. However, it's often underutilized or overlooked for core workouts, which is quite surprising considering how effective it is for ab and oblique exercises.
The cable machine's design enables smooth movements and maintains constant tension across the entire range of motion, which can help strengthen and sculpt your core in ways bodyweight exercises and free weights can not.
With that, it's time to explore the diverse array of exercises the cable machine offers for abdominal and oblique training.
Table of Contents:
First, let's introduce all 17 exercises so you have a clear idea of what's ahead. While 17 might sound like a lot, remember that the core consists of multiple muscle groups (discussed further below), and these exercises collectively target each area comprehensively.
The best cable ab exercises are:
For each exercise, we'll delve into the specific muscles involved, the correct form, and the level of difficulty (the list is in order from easiest to hardest).
It's not recommended to tackle all these exercises in one go. Instead, consider incorporating them into your routine as appropriate. Varying your core training is key to achieving optimal results. After we've covered each exercise in detail, we'll also discuss workout strategies, including a few targeted cable ab workouts.
When you think of cable abdominal exercises, this is more than likely the one everyone thinks about. It's the most straightforward and requires the least room to accomplish. Don't think that makes it any less efficient, it will target your abs better than most, especially the "upper abs".
Main muscles worked: Rectus abdominis (upper abs)
How To Do Cable Kneeling Crunches:
Difficulty: Easy
An alternative to the kneeling crunch, the cable seated crunch is equally as effective, without the need to kneel on the floor.
Main muscles worked: Rectus abdominis (upper abs)
How To Do Cable Seated Crunches:
Difficulty: Easy
The standing crunch is a great standing ab exercise that allows for more range of motion than the three crunch exercises you were just given. But, keep in mind that it will require the most balance as well. This means that you will be dividing your focus, regardless of the large range of motion is great for engaging the entirety of your rectus abdominis.
Main muscles worked: Rectus abdominis (upper & lower)
How To Do Standing Cable Crunches with Straight Bar:
Difficulty: Easy
The steps for this are virtually the same as the standing crunch, but the rope allows for even more range of motion. Moreover, this body positioning allows you to come down at an angle that can better target the "lower abs".
Main muscles worked: Rectus abdominis (upper and lower)
How To Do Cable Standing Crunch with Rope Attachment:
Difficulty: Easy
Anytime you twist your core, you have to be careful not to use a pull and jerk motion. Keep a slow controlled pace for this exercise. It will engage your obliques in a way that other floor ab workouts cannot.
Main muscles worked: Obliques
How To Do Cable Seated Cross Arm Twists:
Difficulty: Easy-Medium
The is a similar exercise but your arms will both hold the handle and be held out straight. It makes the exercise a little harder and involves the abs a little more.
Main muscles worked: Obliques
How To Do Cable Seated Twists:
Difficulty: Medium
This seated twist is in case a bench is unavailable. It accomplishes the same as the cable seated twist, but it may require more balance with your feet out in front of you rather than under you. Arguably it may be harder as well.
Main muscles worked: Obliques
How To Do Cable Floor Twists:
Difficulty: Medium
A cable twist is the most stable form of the twisting exercises, but you must be careful not to pull and jerk. In this standing form, it's easy to get confident and attempt heavier weights. Stay steady and controlled.
Main muscles worked: Obliques
How To Do Standing Cable Oblique Twists:
Difficulty: Medium
The cable side bend is a lateral flexion exercise. It's often neglected by most gym-goers, but it's important for stability and building some strong obliques. It will also help target those pesky love handles.
Main muscles worked: Upper Obliques and abdominal muscles
How To Do Cable Side Bends:
Difficulty: Easy
The addition of the Bosu ball adds balance to the equation. It's a great tool for strengthening your core compression. Often used in physical therapy, it's a reliable way to train your body control.
Main muscles worked: Obliques, Rectus Abdominis, Transverse Abdominis
How To Cable Side Crunch on Bosu Ball:
Note: You can also do this one side at a time.
Difficulty: Easy-Medium
The side crunch is the crunch for your obliques. It is a trunk lateral flexion exercise.
Main muscles worked: Lower Obliques
How To Do Cable Side Crunches:
Difficulty: Easy
With the cable machine, it is important to take advantage of angles. Changing the angles of your lift can target either the upper parts of a muscle or the lower.
While this illustration is the low to high variation of the cable rotational twist, you can't have the 'down-up' without the 'up-down', so be sure to do both if utilizing this exercise in your routine (it can be done on different days, just make sure to do it).
Main muscles worked: Obliques
How To Do Angled Cable Rotation Twists:
Difficulty: Medium
The cable wood chopper will really help with the parts of the oblique that may be hard to target. You can't do this exercise with free weights due to gravity. You can only do it with bands or cables, as you need tension directed correctly.
The biggest difference between this one and the standard rotational twist above is that you'll add a bit of knee drive to create more range of motion and power through the movement. However, like the aforementioned, be sure to move slowly back to the starting position, as this will help you to build strength through both eccentric and concentric contraction.
Main muscles worked: Total core with emphasis on the obliques.
How To Do Cable Wood Choppers:
Difficulty: Medium-Hard
Continuing to take advantage of angles, the cable explosive twist low to high is very similar to the wood chopper, but it is more dynamic and explosive. The difference with this one is that you will go into a bit of a squatting motion for your starting point. It will incorporate your hips and legs into the workout, which your core is needed for explosive work. It is a very athletic movement.
Main muscles worked: Total core with emphasis on the obliques.
How To Do Cable Explosive Twists Low to High:
Difficulty: Medium-Hard
Russian twists are hard enough as is. With the cable, it will burn your core like never before.
Main muscles worked: Obliques, Rectus Abdominis, Transverse Abdominis
How To Do Cable Russian Twists on Stability Ball:
Difficulty: Medium-Hard
The reverse crunch, which is a form of a leg raise, targets the lower abdominals that often get ignored. It's difficult enough by itself, but with the weights, it's going to be a bitter-sweet nightmare.
Main muscles worked: Rectus Abdominis (lower)
How To Do Cable Reverse Crunches:
Difficulty: Medium-Hard
Last but not least is the cable hanging leg raise. This is perhaps the showiest of these exercises, and by far the hardest. A hanging leg raise itself is super hard, so add some resistance and it's next level. The hanging leg raise is often considered the ultimate ab exercise, along with planks and ab rollouts.
If you can't do hanging leg raises with just your bodyweight, don't bother with this one.
Note: Hanging leg raises require a pull up bar, which most cable machines have, but not all.
Main muscles worked: Rectus Abdominis (particularly the lower fibers)
How To Do Cable Hanging Leg Raises:
Difficulty: Very Hard (only expect to get several reps).
Easy Variation: Lying leg raises with pulley attached to your feet.
You can really get creative too! Just be safe.
If you want to do a core workout using only a cable machine, we have two great, well-rounded cable ab workouts for you.
The first is designed to be a proper core workout (like you would any other muscle group) and the second is more of an "ab finisher".
And since we typically recommend variety in both exercises and equipment, we will also run through a core workout that includes bodyweight ab exercises and other common gym equipment and machines.
Note: Ab Rollouts are one of the best core/ab exercises because it works you for trunk flexion (hitting both the upper and lower fibers of the abs effectively), anti-flexion (great for your low back) and anti-extension (again, great for your abs)1. Like the hanging leg raise, it is difficult and hits many muscles at once. We highly recommend adding ab rollouts and hanging leg raises to your routine when you build up enough core strength to perform them safely and correctly. The good news is the cable machine is a great tool to build up to that strength level!
Here are some ab stretches for before and after your workout!
Yes! Cable machines allow for consistent time under tension, incremental progression, greater range of motion, and the ability to work your core through many different angles. Something as simple as cable crunches can greatly enhance your core strength and stability.
To go into more detail...
In the case of the cable machine, it's more about hypertrophy rather than strength. In other words, you're not trying to lift heavy. Instead, you want to lift for fatigue. Ideally, you want to do at least 6-8 reps at a minimum, and that's if you're really pushing the weight or it is a difficult exercise. The optimum amount of reps would be 15 plus or even to failure.
The abs are a muscle that can be trained to failure. Keep rest time low and tension high and you will not need to do tons of reps to reach that.
In terms of progression, you will find that your core strength progresses rather quickly in comparison to other muscle groups. This is because it's engaged in almost every other exercise as well. It is the source of your balance and stability, making it arguably the most important aspect of health.
Feel free to challenge yourself a little more every time you engage in an ab workout. Just as long as you do not compromise your form and repetitions. Keep this in mind when you progress in any form of weight lifting.
Six major muscles make up your core, and they aren't only your abdominal muscles. Your core consists of muscles that cover the front, sides and back of your mid-section (abdomen and low back).
These muscles are:
Among those, the transverse abdominis, internal obliques and multifidus are deep muscles that rest beneath the others. So, while the stars of the show are the rectus abdominis (your "packs") and the obliques, because they are visible (if you have lower body fat), it is paramount that you work your core from the inside out, meaning that you train your core through all planes of motion and actions. After all, there is no point in putting up walls without a strong pillar to hold them up.
On that note, let's look at each muscle and what their main responsibilities are. That way you will understand which muscles are being worked when doing cable core exercises.
When you think of "abs", this is the muscle. The rectus abdominis is your "six pack" (or 2, 4, 8, or even 10 pack depending on your ab structure, as everyone is different). Needless to say, it is a superficial muscle, meaning it is close to the skin, so it is visible with low body fat.
Now, regardless of whether you have 4 pack abs vs. 6 pack vs. 8 pack, the muscle is long, extending from your sternum to the bottom of your pelvis. The muscle is divided into two halves (left and right side) by a band of connective tissue known as the linea alba.
It's main job is trunk flexion and anti-extension, and it assists in lateral trunk flexion as well. So, it is responsible for bending forward, curling up, resisting bending backward, and bending side to side. It also helps to hold your internal organs in place!
Note: trunk flexion means you are moving the body between the ribcage and pelvis (i.e. crunches and leg raises). And while there really is no such thing as upper abs and lower abs, it's simply one muscle, the upper fibers of the abs will be more activated when you bring your shoulders toward your legs (i.e. crunches) and the lower abs will be more activated when your bring your legs up toward your upper body (i.e. leg raises)1. As for anti-extension (i.e. planks), the entire rectus abdominis will be activated.
The transverse abdominis, also called the tranversus abdominis, is a deep muscle that wraps all the way around your abdomen to your spine. It is underneath all the abdominal muscles.
It plays the very important role of abdominal compression, which means drawing your belly button toward your spine, as well as protecting your internal organs by keeping them in place. Moreover, it plays a big role in spinal and pelvis stability. Think of this as your deep stabilizer muscle and protector of your guts! It plays an important role in many exercises because of this (i.e. planks, crunches, rotational exercises, etc.). A bulletproof core starts with the transverse abdominis.
The external obliques run along the sides of the rectus abdominis from the ribs to the pelvis. It is also a superficial muscle, but it's going to take quite a low body fat percentage for them to be noticeable, even if they are well-developed.
Its main job is to twisting and bending your the body side to side, and to also resist twisting and bending - so, trunk rotation, anti-rotation, lateral flexion, and anti-lateral flexion. Moreover, it assists and contracting the abdomen and keeping your guts in place, nice and safe.
The internal obliques are located beneath the external obliques, running along the sides of the rectus abdominis as well. It is a deep muscle that can't be seen, no matter how low your body fat percentage is. But, that doesn’t mean they are not equally as important.
They take on the same responsibilities as your external obliques. However, the muscle fibers run in opposite directions of the external obliques5. So, they work opposite to each other. When rotating to the right, your left external oblique is working with your right internal oblique. This means the internal oblique is a same side rotation muscle whereas the external oblique is an opposite side rotation muscle. Don't worry too much about this, as you will be working both obliques when doing rotation, anti-rotation, and lateral flexion and anti-lateral flexion exercises. It's just interesting to note.
Your erector spinae is more than just your core as the muscle group (it's made up of three long muscles) runs from the sacrum (bottom of your spine/top of pelvis) to the bottom of your skull, right along your spine and back.
Needless to say, it plays a vital role in spinal stability. If you want a strong lower back, which is technically part of your core, then your need to work on your erector spinae.
The erector spinae's main responsibilities are trunk extension, lateral trunk flexion, and anti-flexion. Thus, exercises like back extensions and reverse planks will work your erector spinae.
The multifidus is a posterior core muscle (lower back). It is a deep muscle, running up the spine on both sides from the sacral bone.
Its main job is lumbar spinal stability. It works with the transverse abdominis and the pelvic floor muscle to protect and stabilize the spine. One of the main causes of low back pain is a weak multifidus muscle.
Note: While the cable core exercises above involve some lower back work, you need to do low back-specific exercises too! (Yes, most trainers like to think of the lower back as part of the core.) Check out the 18 back extension exercises to train your erector spinae and multifidus.
Your core is arguably the most important part of your body leading into old age. Set yourself up for a long healthy future by training your core in its entirety. However, do not exert yourself to the point of injury. It's a marathon, not a sprint!
If you've been to literally any commercial gym before, you've seen the cable machine somewhere. It's one of, if not the most, common exercise equipment in a gym, second only to the treadmill, barbell, and dumbbells.
Sometimes called the pulley machine, it's primarily made of an adjustable pulley system with stacks of weighted plates. Moreover, the machine is equipped with two separate pulley towers, independent from one another. You could choose to only use one or utilize both, depending on the exercise.
Everything from the height of the pulley, the weight, and the plethora of grips is adjustable. This allows for a huge variety of exercises, which you arguably can't find in other machines at the gym.
It's important to know that the resistance you receive from the machine will always be consistent with the weight you choose. Unlike free weights, leverage is not really a factor with cables. 20 pounds will feel like 20 pounds throughout the entirety of the exercise. This is because the resistance curve is flat.
For example, with curls, when you curl with free weights, there is a high point of tension when the weight is farthest from your arm at a 90-degree angle, but then a low point of tension when you finally cross that plateau and bring the weight more towards you.
With a cable machine, you will feel the same resistance through the entirety of the curl; there are no high and low points of tension. This helps with consistent and continuous time under tension, overall improving muscle engagement. The same would be true with any cable machine exercise, including core & abdominals.
