Your Core Muscles – Deeper Than You Think

Your Core Muscles – Deeper Than You Think

It seems appropriate to take a swipe at the core since the last two muscle of the month articles were the iliacus followed by the psoas muscle. They equal the ever-popular iliopsoas muscle and are perhaps the epitome of what we call the core muscles. The “core” question came up again this past weekend during a workshop as it often does. You should definitely check out The Psoas Muscle: Ultimate Guide.

What is the core?

What is it? How do we access it? Why is it important? These questions are ones that are asked quite commonly in workshops. As usual, I turn it around and ask the group so I can find out what people are thinking. One of the most common answers is this: “The abdominal muscles are related to the core and it’s important that they be strong for stability of the core.” This is both true and on point, however, there is a lot more to the core than just thinking about abdominals. The abdominals are the most common answer because they are the most obvious. But there are less obvious muscles and less obvious ways that we WANT to think about the core, especially for yoga practice.

The core muscles

Here is a list of muscles that we could associate with the word core:

The core itself

Let’s first define the word core. The word core itself implies deep and central. The anatomical structure that is the deepest and most central is the spine. A lot of what we hear about the core is directly related to the spine specifically, and the torso in general. After all, this is primarily what we want to stabilize with our core muscles.

There is also a dynamic component to the core. This aspect of the core is all about movement and the specific control of movement from the deep intrinsic muscles that move us. Based on my personal experience and training as a bodyworker, I often refer back to Ida Rolf who developed structural integration also known as Rolfing. For her, the spine was the core of the body. The tissues that were the deepest and most intrinsic were considered core muscles. For Ida, the more superficial muscles such as the abdominals were referred to as the “sleeve”, not the core. This is not to say that the deeper more intrinsic core muscles don’t have a relationship with the superficial extrinsic. They do. But she wouldn’t classify them as core muscles in the way that we commonly do today.

Why do we need to know about the core?

Regardless of how we classify any of these core muscles, there is a more important question to ask. Why is it so important to understand the core? In yoga, there are a few reasons that we want to know about the core.

  • Strength and stability
  • Movement
  • Relationship to bandha

Strength and stability

The strength that comes from the core is without a doubt the part of understanding the core that gets the most attention. This is exactly as it should be. One cannot say enough about how important it is to have a balanced relationship with the core muscles. By balance, I mean both strength and flexibility of the core muscles are equally important. This makes them more adaptable.

It is this adaptability that we need at the most unlikely times. For instance, those of you living in places where there is ice on the ground for parts of the year use your core every time you slip and slide on the ice. For everyone, anytime you trip, start to fall, and then catch yourself, it’s the adaptability of your core muscles that is at the heart of what catches you. In yoga, we use this adaptability to move in and out of postures. We also use it when we are faced with demanding strength-based postures such as arm balances, lifting up, jumping, and the like. It is at these moments that we absolutely need the strength and stability of our core so that we can move it.

Movement

When we describe movement from the core, what we’re really asking is: How do I control my center of gravity? It is this aspect of controlling our center of gravity that makes the iliopsoas so relevant to the conversation about core muscles. The iliopsoas is strategically located around our center of gravity, which is located at a spot close to the top and just forward of our sacrum.

Our center of gravity

When our center of gravity is in line with gravity itself, relative to our body parts, we are in balance and in control. When we move from our center, the movements are not only controlled but also expansive and light. We actually end up with two sets of very important qualities of practice: groundedness, stability, or rootedness (mula) and ease, lightness, or graceful movement (uddiyana). Ida Rolf described this as having “psoas awareness.”

The importance of the iliopsoas

This is where the iliopsoas, core, and bandhas all start to mix together from different points of view. These are different perspectives that converge to create a similar outcome. That outcome is a synergy of strength, stability, lightness, and ease during movement. This is often the point where people want to know how to strengthen their psoas, or their core muscles more generally. This is also where people make the most common mistake in my opinion. The mistake is to simplify this into either strengthening or lengthening of the psoas as if it’s that black and white.

I always tell people to establish a relationship with their psoas!  In essence, you want to intend your movement from your core. Now, if you go searching for the feeling of your psoas contracting, you’ll probably miss it. Perhaps it’s easier to simplify things by picking one single solitary spot. How about your center of gravity? If you do this, you will be on the path to understanding how bandha fits into this core muscle puzzle. This is not to say that your iliopsoas is your bandha. Nor does it mean that your center of gravity is your bandha. It’s just a place to focus on until the bandhas do reveal themselves. Here’s a video of Fred Astaire, Ida Rolf’s go-to guy for having psoas awareness.

Relationship to bandha

What is the bandha anyway? It’s often very hard for people to describe what the bandhas are or what they mean by bandhas because it is an experience. Oh, don’t get me wrong. We may be able to intellectually and philosophically describe it, but describing the experience is something different. Being sure of your experience is something different altogether. Because people have different experiences of bandha and discuss it at different levels of understanding, there is often more confusion, not less.

What most of us are able to describe is the physical control that goes with the energetic component of what a bandha is. But this is not really the bandha, this is the outcome or perhaps the quality that is created by the bandha. I personally, am not convinced that I know what the bandhas are. I only know what my experience has been so far.

What are bandhas?

From a philosophical point of view, the bandha is an energetic element within us. So, how do we experience energy? As sensation? As movement? How do we manipulate and/or control that energy? Perhaps we experience it as all of these things. But the first place I suggest we start looking for an understanding of bandhas is with the attention we pay to our breath. Check out my article: How Breathing Leads To Bandhas. After all, it is our breath that we traditionally use as the mechanism to control energy (pranayama).

Bandhas as an object of concentration

It seems logical enough to me that without a level of control of the breath, you are going to have a hard time finding control of energy. That is both the inherent energy that circulates inside of us as well as the energy that we are bringing in through breath. No breath, no bandha. No bandha, no mind control, no development of concentration and focus. This is where we get to the root of the bandhas. In this sense, the bandhas are points of concentration that direct or control the prana. After all, it is our mind that directs prana.

What we are really talking about is a level of awareness. Without concentrating the mind there is no space for awareness. We are stuck in the thought stream that is trying to conceptualize the bandha as opposed to experiencing it. This is no small feat of focus, and I am not professing to have mastered this, but ultimately we are looking toward our CORE! By core here, I am not talking about muscles anymore. I am talking about layers that are much deeper than that and at the same time live within the space of our bandhas, breath, muscles, and core.

Conclusion

There is the literal core of our body, the spine, and then the deepest most intrinsic muscles that surround that. Then heading outward, we find that the superficial muscles also have a role to play in stabilizing and supporting the spine. Although this knowledge certainly moves us forward, it is through movement and the subtlety of movement experience that deepens our practice. Use the center of gravity as a point of mental focus for just one week of practice and see what happens. Email me or post a comment and tell me I’m completely wrong! Most importantly, surrender to the experience, and if you can, don’t conceptualize it or look for any particular outcome. Be more neutral than that.
