The abdominals are made up of 4 separate muscles with different functions. The one we’re all familiar with is the rectus abdominus, commonly known as the 6-pack abs. Unfortunately these are over-emphasized in many traditional ab exercises and are the least effective for strengthening and stabilizing your core. In barre class, I’ve often said “don’t let the little alien pop out” meaning let the rectus abdominus take over your ab work. You know you’re relying on the rectus too much when the abdominals appear to “pop” or what I refer to as the little alien, as in the classic Sigourney Weaver movie, Alien. This abdominal muscle is the primary abdominal muscle that flexes your spine – it bends you forward.
Just underneath the rectus are the external obliques. These run diagonally down from your lower ribs attaching to your hips and rectus abdominus. They help you rotate or twist to the opposite side so the right side external obliques works as you rotate to the left.
Next deepest are the internal obliques. They lie underneath and run criss cross the external obiques. The internal obliques rotate or twist you to the same side so the right side internal obliques rotate you to the right.
The deepest and most difficult muscle to engage and keep engaged is the transverse abdominus. It wraps around you horizontally like a corset from front to back. This along with your internal obliques are important in low back stability. I’m always saying “breathe, breathe” in Pilates and Barre, and that is a sure-fire way to engage your transverse abdominus because it helps you forcefully exhale. As you inhale, your diaphragm extends down into your abdomen and as you exhale it lifts up toward your lungs to force the air out and the transverse helps push it up. Ab work is especially hard to breathe through because of the action of the diaphragm. When your transverse and obliques are tight, there’s no room for your diaphragm to expand downwards. The Pilates method of breathing into the sides and back of your lungs helps with good breath control.
All of the abdominals working together work as a hydraulic lift for your upper torso and spine to help improve your posture. While standing, keeping your attention on lifting your rib cage up off of your hips will help give you a length through the spine as you hold your abdominals in an isometric contraction. The look of flat abs rather than bulging starts with the engagement of the transverse abdominus. With a deeper exhale during the contraction, you’ll get a more flattened appearance and increased intensity. But of course, a flat abdominal area cannot be achieved without a healthy diet! You can have strong abs underneath a layer of fat.
Classes at Align Fitness are NEVER a competition. We are where we are. I often share my struggles with exercises so you can see even those of us doing it for years have our own issues to continually work on. That’s the excitement of Pilates and Pilates-based exercise – it should always evolve. As we become stronger, it does.
I’m a big believer that “flat abs” in terms of how you look in a tight black dress is a nice thought. Genetics, age, diet, your overall health and how much cardio exercise you do can all play a role in whether this can become a reality. Strengthening and flattening your abs while you exercise is more about the health of your back, flexibility of your spine, and how it makes you feel when you’re not exercising. Having a strong core makes you stand up taller and feel better about yourself – whether you have a 26-inch waist or not!
