Muscles of the Core and abs

If you want to know more theory besides this 20-min home abs workout, learn about the muscles of your core and how they work.

The core muscles are the muscles that make up your abdomen, pelvis, and lower back. This is a popular area of focus for many people who want to get fit because it’s easy to see how you can improve this area with simple exercises like crunches or planks.

Rectus Abdominis

The rectus abdominis is the muscle that you can see when you look at yourself in the mirror.

It is also the deepest muscle in your abdomen, and it is responsible for flexing your spine and pushing your ribcage forward. If you have good posture, then this muscle is working well. If not, back pain might be an issue—and it’s important to do exercises that target this area if you want to improve your posture.

Internal Obliques

The internal obliques originate from the inner surface of the lower 8 ribs and insert on the tendinous intersection on the lateral border of rectus abdominis. The internal oblique muscle is a flexor and adductor of the trunk, as well as an internal rotator.

The nerve supply comes from thoracolumbar fascia.

External Obliques

The external obliques are the muscles that run along the sides of your body. They help you rotate your torso, flex your spine, and bend to the side.

When these muscles contract they pull down on the rib cage and compress it slightly (which makes it shorter).

Transverse Abdominis

The transverse abdominis is a deep muscle that wraps around your midsection. It helps to stabilize your spine and compress the abdominal cavity, which increases intra-abdominal pressure to help protect internal organs from injury.

To contract it, use the following breathing technique: breathe in deeply through your nose while expanding your belly outwards as far as possible without straining; then exhale slowly through pursed lips (as if you were going to whistle) while contracting your abdominal muscles inward towards the spine.

Hold this contraction for 3 seconds, then release and repeat 3 times.

Erector Spinae

The erector spinae are a group of muscles that run along the spine and function to keep it straight and upright.

They also help rotate your spine, bend it forward, and bend it backward. If you’ve ever had trouble bending over to pick something up off the ground or if you’re unable to touch your toes without rounding your back, this might be why.


The core is made up of more than just abdominal muscles. It also includes muscles in the back, spine and hips, as well as those in the arms. The main function of these muscles is to provide stability for movement and improve balance. This blog post discussed each muscle group individually along with its functions and exercises that work on each one specifically.

Now that you know all this info, you understand why it is important to consistently do this 20-min home abs workout to strengthen your body and keep it safe from injury.
