The True Depth of Your Core and How Yoga Can Help Develop Core Strength

I hear it all the time “I really need to work on my core strength”. People say this for many reasons: back pain, a few extra pounds, balance, poor posture, a general sense of dissatisfaction. Most of the time when saying this they’re referring to the front side of the abdomen. And let’s face it, it’s the part we can see so it’s the part we pay attention to the most! But what if I told you that your actual core was not just your abs AND, maybe even more importantly, your core was actually something to think about in 2 different depths in your body? Here’s a simple introduction to two possible ways to think about the true depth of your core and how yoga can help develop core strength.

Let me preface everything I say here with the following: your body is an incredibly complex system and no one system can be separated out entirely from the rest in practical application. This is also true for your muscles. We can take individual muscles or groups of muscles into consideration as a model to start to understand our bodies better, but just know that the interrelationships between individuals and groups within the whole is complex and beyond the scope of a single blog post. What I give you below is a model for how to think about and work with this one system within the body that we know as our core.

Deep Core

As I mentioned above, I really think about the core in two different ways. The first way is what I would refer to as the Deep Core. In anatomical language, what is superficial is closer to the surface (in other words, just under your skin) and what is deep is, well, DEEP! So this first way to think about core involves some things that you can’t necessarily touch with your hands.

The first of those is your SPINE. In discussions of Core, this is often overlooked, but if we consider the core to be at the center of our body, we have to first consider the bony structure that is not only at center, but is an attachment point for many muscles that we might think of as Deep Core muscles. It’s also worth noting that most of us, because you can feel your spine through the back side of the body (just put your hand on the back of the base of your neck. That bony bump that sticks out is actually your C7 vertebra), don’t have a good understanding of just how deep the spine goes into the abdomen. I can’t give you definite measurements, but trust me, it’s pretty deep!

Now we get to the muscles of core and here is where, in my mind, I start to make some distinctions. Generally speaking, the muscles that run along and attach to the spine are muscles that mostly create spinal (or deep core) stability. Key among these is the psoas. This large muscle is often thought of as a hip flexor, but in reality, it’s PRIMARY function is to create stability and absorb shock in the spine. While it does serve a small part in hip flexion (remember, complex system) we can see that the bulk of the muscle is much more focused on the spine, simply by looking at how many more muscle fibers are near or attaching to the spine versus the hip joint.

There are many other deep muscles that stabilize the spine include the amazing network of interspinal muscles and the erectors. Rather than getting bogged down with names and details, simply understand that there is the deep level to core that is centered near and surrounds the spine.

Superficial Core

There is this second level of core as I think of it. This is the one that most of us think of that includes the abs. However, a key concept here is, just as in the deep core, it’s not just the front! Generally speaking, the Superficial core is a full circumference network of muscles around the abdomen that mostly create movement. This includes your abs on the front but also includes your obliques (the sides of the cylinder), your lats (the back) and other layers of muscle. These muscles are fairly large and while they do contribute to stability, they can mostly be thought of as being responsible for movement such as flexing your spine, extending your spine, twisting and side bending. Therefore, to focus on only one set of these muscles is to loose sight of the full picture of what constitutes core.

So we have a Deep Core network of muscles that is close to the spine and generally creates stability, we have a Superficial Core network of muscles that is closer to the surface and generally creates movement. This basically describes a cylinder that has a center within it. Something like this:

So what about the top and bottom?

In my mind, the top and bottom are shared between these two levels (Deep and Superficial) because they cover both. The bottom is the network of muscles that make up the pelvic floor. The top is your breathing diaphragm. If you’ve never seen it before, it looks something like this:

The umbrella like shape of this muscle puts a lid on our cylinder, connects to the spine but also connects in close proximity to those Superficial Core muscles around the outside. The pelvic floor works similarly. These structures create stability but are also key in movement throughout this complex system.

What It All Means

With this understanding that there are two main layers to our core as well as a top and bottom, we now see that the things we might always think of when it comes to core work, namely sit ups, really are addressing only one thing - the superficial muscles on the front side of the abdomen. Now also try to imagine that this was the ONLY thing you focused on when trying to strengthen your core. It becomes obvious right away that this would create an unhealthy and unhelpful imbalance. We need to work all these structures to bring a balance of strength and flexibility to the entire system in order to be well, similar to any other point of focus in the body.

How Yoga Can Help

While a vinyasa yoga practice can’t necessarily address the full picture of core strength, there’s a lot that we CAN do to holistically address the deep and superficial core in our sequencing as teachers and in our practice as students. Here are some ideas:

• Rooting down through the feet in standing postures - this kind of engagement, especially before transitioning from close to the earth into a standing posture (think moving from low lunge to Warrior 2) can activate those stabilizing muscles of the deep core including the psoas. There is a complex network of muscular connections between the psoas and your feet (see the work of Tom Myers if you’re interested in learning more). When you engage in this way you’re helping to support the spine through transitional movements and creating that deep core stability those deep core structures are there to do. (For more about the benefits of rooting down in standing postures, see this blog post.)

• Lifting high enough in Ardha Uttanasana (half way lift) - it’s a posture most people hardly give a second thought to in their practice, but actually lifting up in this posture can help to work the back body muscles and create more strength. Even better, think about that support coming from the front and the back. More on that here.

• Create twisting actions without leverage - many yoga practitioners use their arms to help create leverage for deeper twists. This isn’t wrong. However, if you want to build core strength, especially in the muscles of the core that create rotation, consider doing your twist WITHOUT the arms involved. You won’t go as deep, but you’ll certainly create more strength in these important side body muscles.

• Incorporate more locust poses into your vinyasa - resisting gravity is a key way to build strength in a yoga practice and there’s almost no better pose to embody that than locust. When working with this posture, be sure to do your best to not just bend the knees when you lift the legs. See that the lift is actually coming from the use of your back body muscles like glutes (they’re part of your core!) and hamstrings.

• Use the breath in coordination with movement - This is especially useful in movements that create a lot of force or load in the body. One of my personal favorites as a person with back injuries is to EXHALE on the way up to standing from a standing forward fold.

Three HUGE Benefits of Standing Yoga Postures

Standing yoga postures are some of the most often practiced yoga postures across many styles and traditions of yoga. But have you ever taken a moment to step back and wonder WHY these postures show up so much? I honestly hadn’t until recently, but when I did I realized they really offer us some amazing benefits when we give them the attention and focus they deserve. Here are three HUGE benefits of these yoga poses and some ideas that might help you bring them into better focus and appreciation the next time you get on your mat.

Standing Yoga Postures Stretch and Strengthen Large Important Muscle Groups - Whenever you’re working in standing yoga poses you are either stretching or strengthening some of the largest and most important muscle groups in your body. These include all the gluteal muscles (did you know that there are three of them per side?), the hamstrings (there are three of them too!), the quadriceps (bet you know how many of those there are! 😉) and the calf muscles, along with some other smaller muscles that are in the same general neighborhood. Depending on the posture you’re doing, you may be flexing or extending key joints in the legs like your ankles, knees and hips helping them to move through their full ranges of motion.

Why is that important? If you’ve ever had the experience of being unable to walk without assistance you know why. The full functioning of our legs in our life is an essential key to a life well lived and part of what makes us fundamentally human. Think about how many things, both simple (getting to the bathroom) and more complex (getting around the grocery store to get everything you need from the top shelf to the bottom one), that you wouldn’t be able to do or would be extremely difficult without working legs. Certainly, many people overcome this obstacle in amazing ways, but if you have two functional legs this family of postures offers a great variety of benefits to keep them healthy and working for you for a long time to come!

Point of focus for practice: Cultivate a sense of the muscles of the legs engaging (contracting) in your standing postures. The ones that are in a lengthened position might build a bit of eccentric strength and the ones that are already stabilizing might build a bit of isometric strength, both of which are important and beneficial for many reasons.

Standing Yoga Postures Can Help Train Your Body to Balance - The standing postures that require us to stand on one leg are probably the most obvious that come to mind here, but if you’ve wobbled in your warrior or triangle pose you’ve actually experienced this benefit as well. Have you ever considered how incredibly quickly the messages between the sense receptors in your feet and legs have to travel to your brain and back to help you maintain your position in any of these postures? It’s so fast we don’t even notice it most of the time. The only time we tend to notice is when we DO feel that wobble happen. But here’s the great thing - those moments of wobble are creating experiences that train your body to respond and correct more accurately and more quickly by developing core strength, kinesthetic awareness and proprioception. It’s something that not a lot of people practice once they learn to walk. Living in New England, especially in the winter months, I really think of this as one of the greatest benefits of our practice. When you’re doing that winter shuffle to the car you have a much better chance of recovering if you start to slip than you would otherwise. That doesn’t mean accidents won’t happen, but it sure does stack the odds more in your favor!

Point of focus for practice: The next time you wobble and recover, instead of cursing yourself or getting frustrated for a weak moment, turn some gratitude toward your incredible body for being able to compensate and correct when needed. Then consider where it is you might need more engagement to help you maintain stability.

Standing Yoga Postures Can Make You Feel Grounded - Life has definitely shown us some serious challenges recently and a sense of not knowing when the next shoe might drop or the ground beneath us might shift again may still be operating in the back of our minds and hearts. [Incidentally, if that’s something that’s really bothering you, check out PSTEC to get some relief.] When we practice standing poses we have an opportunity to allow ourselves to make a deep connection with the steadiness of the earth beneath us through the parts of our body that were built for the job, our feet and legs! I’ll often draw your attention in class to rooting down into the earth through the feet before coming into a standing posture or again once you’re there. Have you ever noticed the rebounding effect that happens when you do so? There’s an amazing relationship there. You press into the earth and she gives you the energy and stability to grow and stand tall. That feeling and that relationship can’t be underestimated. The Warrior poses are called that for a reason! When you do them, you embody the strength of a warrior. That can be a great reminder of that quality existing inside of you when you’re feeling like anything BUT a warrior.

Point of focus for practice: The next time you come into a posture like Warrior 2, before you move into it, press down through the feet and see if you can feel that rebounding effect through your torso. It might be a sense of lightness or ease that allows you to float up rather than feeling like you’re trying to drag your torso away from the ground. You may also find you arrive in the pose with a greater sense of steadiness.

How a Modern Interpretation of Foot Placement May Help Your Standing Yoga Postures

When I began my teaching career I noticed right away that many students had stability problems in standing yoga postures like Warrior 1, Warrior 2 and even Tadasana. As I continued to observe my students and experimented in my own practice, I found time and time again that a wider base of support seemed to eliminate these issues almost instantly. Depending on the lineage of teaching that a student and teacher may have come through, confusion may still remain as to appropriate foot placement for individual bodies in these postures. In this post you’ll find an anatomical explanation for this modern interpretation of foot placement and how it might help you feel more steady and at ease in these commonly practiced standing yoga postures.

Traditional versus Modern Interpretation

I often make the joke to private students when we start to work with these kinds of details in their postures that “this practice was created by skinny little Indian men, and honey, I’m an American woman and I have hips! I need space!” (If you’ve never met me in person I’m nearly 6 feet tall and weigh about 185, so I am neither small nor skinny!) All joking aside, what I’m pointing out is something very important to this understanding of foot placement - the traditional interpretation of the postures revolved around the narrow pelvis of the people that “created” the postures and the people that were being taught. Students of yoga in those days were of typically of Indian decent, young and male. They therefore had a naturally more narrow pelvis and were taught a more narrow placement of the feet in standing postures.

Anatomically speaking, our knowledge of an individual’s unique differences in their anatomy and how they might affect their practice has improved in the last century. We now know that the female pelvis is wider than the male pelvis, primarily to accommodate childbirth. This google search will give you some images and articles to make this more clear. But the important part for our asana practice is that, generally speaking, our unique anatomical make up, our general range of flexibility and the shape of our frame will have a great deal of affect on the stance we take in our standing postures. The majority of yoga practitioners in the US are female and with our more recent anatomical understanding many teachers, myself included, have begun to teach foot placement in standing postures in a more anatomically informed way.

Let’s give you some examples so you can start to put this into practice. And please bear with my rather rudimentary illustrations! And also bear in mind, the use of traditional vs. modern is NOT a value judgement, but a way of making a distinction.

Let’s take Tadasana (Mountain Pose) for instance:

In the traditional interpretation of the posture, the big toes would come together to touch as you stood at the top of your mat. Some people would even bring their inner heels together. Let me be very clear here: THIS IS NOT WRONG. For many bodies this won’t be a problem. For many other bodies this may feel like a very narrow base of support that isn’t at all grounded. In my body, this additionally creates a tension in my outer hips that doesn’t feel beneficial.

Also, when I look at the center line of my foot, it is offset compared to my pelvis. I can tell because when I feel my hip points (the two bones you might be able to feel if you palpate the front of the pelvis), if I were to draw a straight line down to the center of my foot, that line hits more towards my outer ankles. So instead, I take my feet “sit bones distance apart” (I often have people measure this by bending forward and taking two fists together between the arches of the feet. It seems to work well.) which gives me a broader base and more appropriately aligns my body. So it would look more like this:

With this broader base I’m more able to hold my ground, or be more firmly grounded in this pose that is supposed to embody stability.

This wider foot placement in Tadasana also translates into other common standing poses. Tadasana, is after all, the foundation for every other yoga posture. Take Warrior 2 for example. Here’s what the traditional foot placement would look like:

You can see from the lines on this mat (thank you Liforme!) that the heel of the front foot would have bisected the arch of the back foot. (I have also heard it described slightly wider, so that the heel of the front foot would have lined up with the heel of the back foot in traditional teaching.) This might give a practitioner with wider hips a feeling of, what I often call “walking the tightrope”; the base of support is too narrow to be stable. This often shows itself not while the practitioner is in the pose, but when they are making the transition up into the pose from a lunge, for example. There’s a wobble that happens in that transition and I’ll often see students reflexively step the back foot wider to catch themselves! What they’re instinctively doing is creating a stance more like this:

This comes into play again when we look at Warrior 1. Again, the more traditional placement would look like this:

But for many bodies, this foot placement becomes problematic when the practitioner attempts to make the transition into the pose from a lunge and/or places unnecessary forces into the knee joints in particular as the pose is held. With Warrior 1, as the pelvis rotates toward the top of the mat, the narrow stance may not allow for much rotation. With the pelvis unable to rotate and force still being applied (a discussion for another day), that torque has no where to go but to the next available joint, which is the knee. Unfortunately for our poor yoga student who is fighting to do what is asked, the knee is a hinge joint and does not lend itself to rotation. Chances are, they feel this as something happening IN the joint, a thing we typically want to avoid in a vinyasa yoga practice. This can all be avoided by stepping the feet wider like so:

With the broader stance pictured above, there’s greater freedom for the rotation of the pelvis, the integrity of the knee is no longer questionable and there will be a greater sense of stability in the pose overall.

What Does This All Mean for You?

To apply what you’ve learned here you might take the time to experiment with these different foot placements outside of a class. Start with Tadasana and see how your body feels with the two different foot placements. Depending on your specific body type and shape, you may find one that feels more stable and easeful than another. Then do the same experiment with Warrior 2 and Warrior 1. Take the time to really notice the effect on the joints of the legs in particular and your sense of stability. Do you feel like your “walking the tightrope” or if a strong breeze came by would you be steady? As with anything in yoga, the proof is in the experiment within the laboratory of your own body, life and practice!

I’m considering offering a workshop on this topic in the near future. If you’d be interested in such an offering, let me know in the comments below or send me an email!
