Say goodbye to guesswork and take a well-informed, effective approach to abs training.

In this blog post, we’ll show you the best abs machine exercises for each abdominal muscle group and how to do each one correctly. We’ll also provide a sample workout routine and tips.

The Anatomy Of Your Abs and Oblique

Your waist comprises two muscle groups: the rectus abdominis (known as your “six-pack” muscles) In the front and the obliques on each side.

To build the impressive six-pack abs, first we needed to understand the anatomy and functionality of the abs. It is helpful to perform the ab exercises on the gym machine to the best level.

Abs and Obliques Muscles

Rectus Abdominis

The rectus abdominis is a paired muscle running vertically down the front of the abdomen. It is commonly referred to as the “six-pack” muscle.

The two rectus abdominis muscles (one on each side) are encased in a sheath of fascia that forms the central dividing line down the middle of the abs.

External And Internal Obliques

The external and internal obliques are located on the sides of the abdomen.

  • The external oblique is the outer visible layer that passes run diagonally on each side of the rectus abdominis.
  • The internal oblique muscles lie under the external obliques and run into the lower back or erector spinae.
  • The oblique muscles play a crucial role in torso rotation and lateral flexion, aiding in activities like twisting and bending sideways.


The core comprises not only the abdominal muscles but also the muscles of the lower back, hips, and pelvis, working together to stabilize and support the spine.

The abdominal muscles work in synergy with other core muscles to provide stability, transfer force, and maintain proper posture.

7 Best Gym Machines For Abs Workouts

Many gym-goers want strong, toned abs. While crunches and planks are effective bodyweight exercises, it is important to consider abs machine exercises when developing your core training regimen.

Machines help isolate muscle groups, improve form, and add resistance to challenge your abs better. Here are 7 gym machines that you can use for a complete abdominal workout.

1. Cable Machines For Abs

Cable machines are a popular type of gym equipment that can help you build your core and tone your abs. These machines have cables and pulleys that you can change to do different abs exercises in different directions.

Cable machines provide several benefits, including constant tension, versatility, and adjustability.

They help you work on specific muscles or muscle groups, balance out muscle imbalances, and improve your mind-muscle connection.

Cable machines are a safe way to exercise for people who are new to it or who have some experience.

Cable Machine Abs Exercises:

  • Kneeling cable crunches – Primarily focuses on the rectus abdominis.
  • Rotational side crunches – Twist obliques, pulley to the side
  • Standing cable wood chop – Engages the obliques, rectus abdominis, and also works on rotational strength.
  • Cable reverse crunches Targets the lower abs and core stabilizers.
  • Standing Cable Pallof Press: Excellent for core stabilization and works on the deeper core muscles

How To Do Cable Crunch

Cable crunches, also known as kneeling cable crunches, are a weighted Crunch variation that targets your ab and core muscles. Perform cable crunch at the gym by kneeling in front of a cable station with a pulley attachment.

Doing Abs crunches exercises on a cable apparatus at a gym offers one huge advantage over doing them on the floor.

The cable increases resistance, enabling you to train to failure using heavier weights and fewer reps—this increased emphasis on strength and hypertrophy.

Cable Crunch
  1. Attach a rope to the top pulley of a cable machine. Kneel in front of the machine.
  2. Grip the rope handle above your head with both hands about shoulder-width apart.
  3. Sit up straight with a slight arch in your lower back. Keep your head aligned.
  4. Push your hips forward slightly to engage your core. Maintain this posture.
  5. Exhale and slowly crunch down. Keep your chest up and contract your abs.
  6. Focus on using your core to pull the rope down.
  7. Squeeze your abs hard at the bottom of the motion. Avoid pulling too far down.
  8. Inhale and slowly return to the start position in a controlled motion.
  9. Repeat for the desired number of reps.
  10. Focus on proper form rather than speed. Breathe steadily and keep your lower back straight.
  11. Start with lighter weight and progress by adding plates to increase resistance.

2. Captain’s Chair

The Captain’s Chair, also referred to as a vertical knee raise station, is commonly found in gyms. It has a tall frame with armrests and back support, so the user can hang freely.

Although the chair uses the same muscles as a hanging leg raise, it supports your back, which makes it more comfortable for most people.

After performing a small study, the American Council on Exercise named the standard Captain’s Chair crunch one of the most effective ab exercises for stimulating the abs and obliques.

Some of the exercises that can be performed on the Captain’s Chair include:

  • Straight leg raises: Raise legs up together to 90 degrees.
  • Bicycle crunches: Bring alternate knees to the chest
  • Hanging knee raises: Bring bent knees to the chest.
  • Oblique knee raises: Bring right knee to left elbow, twist obliques
  • Flutter kicks: Rapid, small kicks replicating swimming
  • L-sit holds: Hold the leg raised at 90 degrees.
Captain Chair Straight Leg Raise

How To Do Captain’s Chair Straight Leg Raise

  • Step into the Captain’s Chair apparatus. Position your back flat against the back pad, and place your forearms on the armrests.
  • Allow your legs to hang straight down. Keep them straight and together.
  • Engage your core muscles to stabilize your spine.
  • With a controlled motion, lift your legs up in front of you.
  • Aim to raise your legs until they are parallel to the floor, or as high as you can go without compromising your form or causing back strain. The higher you lift, the more intense the exercise.
  • Once you reach the top of the movement, pause briefly.
  • Then, slowly lower your legs back to the starting position.
  • Controlled movement is key, so avoid letting your legs swing or drop suddenly.
  • Exhale as you lift your legs, and inhale as you lower them.
  • Aim for a set of 10–15 repetitions, or as many as you can do while maintaining good form.
  • As you get stronger, you can increase the number of sets or reps.

3. Oblique Machine Twist

The Oblique Twist Machine, also known as the Rotary Torso Machine, that’s specifically designed to work on the oblique muscles on the sides of the abdomen.

It is a versatile piece of equipment that can help you achieve a stronger and more toned core.

These machines typically consist of a seat that the user sits on, and a cushioned handle in front that the user holds onto.

The machine lets you rotate your trunk against resistance. This effectively which targets the muscles of your core, including the obliques, quadratus lumborum, rectus abdominis, and transverse abdominis.

Ab exercises you can do with the oblique twist machine:

  • Seated machine oblique twist
  • Standing machine oblique twist
Seated machine oblique twist.

How To Do Standing Machine Oblique Twist

  1. Stand on a twist machine with feet hips apart and hold the machine handles.
  2. Assume a normal posture, with your back straight.
  3. Exhale and using your abdominal muscles twist the pelvis slowly to your right, as further as you can, tensing your abs.

4. Pull Up Bar For Abs Workout

A pull-up bar is a versatile piece of exercise equipment that can be used for various upper body exercises, including abs. It is usually mounted in a doorway or attached to a gym cable machine or power rack. It is simple to use and can be done at home.

Hanging leg raise is one of the most popular abs exercises that can be done on the pull-up bar. This exercise works your lower abs and hip flexors.

It enhances basic strength and hypertrophy of core muscles that assist in movements like squats, cleans and snatches, bracing, and more.

It is one of my favorite abdominal exercises that I used to train and build strong core muscles after a leg workout.

A 2014 study demonstrated that leg raises produce an impressive level of muscle activation, with over 130% maximum voluntary contraction (MVC) in the rectus abdominis (the “six-pack” muscles) and 88% MVC in the external obliques. These findings highlight the effectiveness of leg raises in targeting and strengthening the core muscles.

Pull Up Bar For Abs Workout

Here are some abs exercises that can be done with a pull-up bar:

  1. Hanging Knee Raises: Excellent starter exercise for beginners. Lift the knees towards the chest.
  2. Hanging Leg Raises: A more challenging variation of knee raises. Keep the legs straight while lifting them.
  3. Toes to Bar: For advanced users, toes to bar requires lifting your legs all the way up to touch the bar with your toes.
  4. Windshield Wipers: Rotating your raised legs from side to side in a windshield wiper motion. It’s an effective way to target the obliques.
  5. Hanging Scissor Kicks: Alternating each leg up and down in a scissor motion, this exercise engages the lower abs and hip flexors,
  6. Hanging Around the World: Involving circular leg movements. It’s great for hitting the abs from multiple angles.
  7. Hanging Oblique Raises: lift your knees towards your side. Effective to train the obliques.

How To Do Hanging Knee Raise

  1. Grab a bar with an overhead grip, with the hands slightly wider than shoulder-width and your knees slightly bent.
  2. Keep your core and glutes tight to keep your back and hips in the correct position.
  3. Lift your legs and bend your knees as you go up. This will make your knees closer to your chest. Also, round your lower back to move your glutes forward.
  4. Pause for a second and slowly lower your legs back to the starting position without swinging. Inhale as you go down. 
  5. Continue for the desired reps.

5. Incline Bench To Train Abs and Oblique

An incline bench is an exercise equipment that has an adjustable bench slanted at various angles. The inclination adds an additional level of difficulty to exercises compared to a flat bench.

The angle of the bench can be adjusted to increase or decrease the difficulty of the exercises.

One of the most popular exercises that can be performed on the incline bench is the incline bench sit-up. Here are some abs exercises that you can do with the incline bench.

  • Incline Sit-Ups
  • Incline Leg Raises
  • Incline Reverse Crunches

How To Do Twisting Sit-Up

It is a challenging exercise for developing the upper abs. This position causes your body to work harder, since you have to work against gravity and through a wider range of motion.

It’s a great exercise for intermediate to advanced lifters because it is moderately challenging but very effective for its intended purpose.

  1. Sit on the decline bench, hook your feet under the pad, lean back, and position your hands behind your head.
  2. As you sit up, twist your torso, directing your right elbow toward your left knee.
  3. Reverse the motion and lower your torso back to the starting position.
  4. During the next repetition, direct your left elbow toward your right knee.
