Classical Greek heroes and figures featured prominent abs.

Since then, we have continued to associate abdominal muscles with health, strength and beauty.

That’s why there are a thousand advertisements that promise you flat abs:

  • Accessories (such as cushions, abdominal machines and ab wheels)
  • Devices (such as electrostimulators)
  • Methods (8 minutes abs, Runtastic 6 pack, etc.)

Traditionally, these exercises and accessories focus on stable and low-mobility ab workouts. Lying on the floor and flexing the spine to work on a focused area in the center of the abdomen.

These workouts neglect the main function of the core muscles. They don’t work the abs in a way that the body understands and thus is does not allocate resources to to their growth.

The abdominal muscles stabilize the body, protect the back and deploy strength.

The movements of our extremities originate in our core.

This is the reason boxers need strong abs if they want to hit hard. They also protect key organs for our survival: contracting during an attack.

If you want to strengthen your abdominal muscles you should make your body understand that it is necessary. This is the fastest way is to simulate its true function.

Muscles of the abdominal area

The abdominal muscles overlap one another.

Their fibers cross over, which gives stability to our entire core.

It also keeps the viscera in place, aids in breathing, and protects the spinal column.

Let’s do brief review the main muscles of the abdomen. 

Oblique muscles of the abdomen

External oblique muscles of the abdomen

The external oblique is a broad, thin and superficial muscle. It is the biggest of the three muscles that form the lateral anterior part of the abdomen. 

The internal oblique lays just below of the external it’s smaller and it’s fibers run perpendicular to its larger brother.

The function of these muscles is to pull the chest downwards. The contraction of one side will cause a lateral flexion of the body. If both sides contract, your chest pulls downward in a bend.

They also asist breathing during exhalation.

Transverse abdominal muscle


The transverse muscles are the deepest of all the core muscles. They provide stability to the entire lumbar region.

They have two functions. The first is to perform the rotation of the trunk when only one of them is contracted. The second occurs when contracting both of them, which causes you to exhale.

Straight muscle of the abdomen


The most famous of the abdominal muscles, it’s what creates a six pack. Its function is trunk flexion, but they also look good!

Iliopsoas (Hip Flexor)


This abdominal muscle is an important one that isn’t visible. It is the muscle most related to the protection and stability of the spine and rotation of the trunk.

3 Key Functions of Abdominal Muscles

Anchor point: The muscles of the abdomen offer a stable anchor point to the rest of the body.

Coordination: Abdominal muscles offer optimal coordination with other muscle groups. This gives us an optimized range of movement of the limbs and back. So you get the greatest amount of strength with the lowest amount of expended energy.

Protection: A toned abdominal wall helps protect the internal organs. They’re like the ribs of the intestines.

The secrets on how to make core strengthening exercises effective

  • Choose exercises that you can do with good technique. As explained before, the core creates good posture. If your exercise technique is bad, your posture can be affected.
  • Choose workouts that move you in lots of directions. Remember that we have more core muscles than the straight muscle of the abdomen. You will need to exercise extensions and rotations to workout all of them.
  • Exhale as you workout. Especially if you are a girl, you don’t want to generate too much pressure and weaken your pelvic floor. In fact, it’s good to explore hypopressive exercises.
  • Make sure your core is stable. To check it, maintain a plank position and see how long it takes for you to start trembling.
    • If less than 30 seconds, you should start with some basic exercises.
    • If between 30 and 75 seconds, then you have a regular core and you can do a combination of simple exercises and one or two difficult ones.
    • If between 75 and 120 seconds, you have a healthy core. 50% of the exercises in your routine can be difficult exercises.
    • More than 120 seconds and you have a strong core. your routine can include up to 75% of exercises that are difficult.
  • Remember that core exercises must meet three essential requirements:
    • They should control your posture
    • Stability in positions
    • Strength in movements.

Best practices for core strengthening exercises

  • Work abs with your limbs. Remember that your abs are the anchor point of your limb movement. Use unilateral loads so you work out your trunk.
    Also, difficult flexing and pulling arm exercises are demanding for your abs.
  • Do balance exercises. The abs are integral in maintaining your posture. Balancing exercises on unstable surfaces will work them a lot.
    If you don’t believe us, try it! Keep your balance on any unstable site and feel your abs work.
  • Wake up your abs with a few taps. The abs serves as protection, so a direct tap while you work them should signal that they should improve.
    It does not need to be strong, simple touches serve as a reminder.
  • Forget the 500 repetitions (at least at the beginning) If you think about it, it does not make sense to repeat the same movement 500 times. Instead, you should try to try to reach exhaustion with less repetitions. Increase intensity, position and loads. You will see how much more effective it is. 
  • Diet is essential. Remember the hard work you put into your core strengthening exercises won’t be visible unless you also add in a good diet to cut fat around your middle.
