Archives For Eyal Lederman

I was listening to Eyal Lederman discussing his article “The Myth of Core Stability” yesterday. I have taken issue with his article before now, for various reasons, not least because the article is essentially rubbishing something which Dr Lederman fails to define – without a clear definition, rubbishing the concept becomes rather easy. Now, however, it occurs to me that the underlying trouble is that no-one can define ‘core’, as it relates to human anatomy, in a way that will receive broad agreement.

Try an internet search for a definition. The core is the trunk. The core is the transverse abdominis, deep multifidi, pelvic floor and diaphragm. There is an upper core and a lower core. The core is the trans abs, obliques and lower paraspinals. There’s a front core and a back core. The core is from the neck to the knees. (For extra fun, try a search for ‘weak core’ – eye-opening stuff, to be sure).

Core is something that goes to work before we move, right? The nervous system sends a message to the core to tell it to stiffen prior to moving our limbs, and that way we don’t destabilise our lower backs – isn’t that how we work? And this happens in fractions of milliseconds. Maybe we ‘know’ this because EMG studies have been done that show the order of firing of muscles yet, as Dr Lederman points out, to get an accurate picture of what happens you would need to have an EMG for every muscle, for every movement, to really see what happens (and then you’d only be seeing what happens in that single subject). This would also assume that what we learn from anatomy books about the location and role of muscles is not only universal but also exactly accurate, and not simply a means of dis-integrating an integrated system.

Pilates, as I understand it, is about whole body movement. And with good reason – there are very few movements that are not whole body. You can lift you arm without moving anything else, but that doesn’t mean that the rest of your body doesn’t respond. Pilates is a holistic practice because movement is a holistic practice, even when you attempt to isolate joints or muscles. To paraphrase Ido Portal, when you tug on a shirt, you tug on the whole shirt. Our whole body responds to movement, as an integrated organism.

The idea of core relies on the belief that muscles are laid down in layers, from the skeleton outward to the skin. ‘Like the layers of an onion’, as one explanation of ‘core’ offered. This sounds like a mechanism, not the model of an integrated biological system. We are animals (however much we may desire to elevate ourselves above such lowly status) and we don’t move in the way that a mechanism that we could build would move.

What if (and I strongly believe this to be the case) your brain knows how to move your body far better than any externally derived input, and your belief in core activation actually inhibits your natural functioning? Did you manage without a core before you knew you might have one? If you have been injured, did you know about your core before or after the injury? Did your discovery of a core influence your injury recovery? Has anyone recovered from injury without discovering they may have a core?

To use the word ‘core’ in relation to movement, exercise, or health feeds a picture of a hierarchy and/or layering of muscles which, if out of order, will lead to almost certain dysfunction. We are animals. All things being well we move as animals do, as whole beings. What is the level of movement dysfunction amongst other mammals? Do they show signs of missing core exercises, of having poor core control? (What would you suggest if they did?)

Core is anti-Pilates. It is a term that I hear most from people who are describing their own inadequacies or failings, as told to them by either media or medical professional. The prescription, I would respectfully suggest, is more likely to be ‘more varied movement’, or ‘move with an awareness of the ground and your environment’ than it is ‘practice engaging your core’. Just as walking down the street ‘engaging your core’ will create constipated movement and breathing patterns, so will practicing Pilates as if it requires ‘core activation’.

What to say if you’re banned from saying ‘core’? Could this be a good moment to focus on the outcome (the movement, that is) that we want for our students/clients? Instead of an internal cue, what would be an externally oriented cue?

Thank you, as ever, for reading.
