Know Your Core

A big part of my time in a session involves education.  Education and information for the client (anatomy, pain science, muscle function, etc.), and reeducation of the client's neuromuscular system. Our body is super smart; it finds a way to move and will continue to do this movement over and over again even though this particular strategy may not be the most effective for the health of the tissue or system.  Part of my job as a therapist is to see the non optimal strategy and teach the client how to reeducate their system for health and longevity.
One of the biggest areas of poor strategies and body confusion is at the core. The core is an area of the body that has a lot of hype.  Fitness pros are making bank teaching people how to strengthen their core to look ripped and lean. Unfortunately a "fit looking" core doesn't mean it is a functional core.

The Core

The core is the area where your head and extremities attach. We have an inner core: throat, diaphragm, deep abdominal (transversus abdominis), pelvic floor, deep back (multifidus) AND I personally like to include the psoas. The outer core is all of the other muscles.

Understanding how the core works

To understand the core, I like to start with the breath.  Little do we know that many of us are 1) holding our abs in all day so that the muscles don't get to fully move and relax or 2) barely breathing.
In an ideal world, when we are at rest whether sitting or in standing, all of our muscles should be at their resting length. Muscles can generate the greatest amount of force at their resting length: not too short, or not too long.

• Holding in abs:  When we are holding are abs in all the time, the muscles are already contracted in the shortened position.  When the body moves and the muscles are required for support, there is not adequate movement (because it is already shortened) to generate the greatest force.  That means that the smooth orchestration of timing, coordination of the muscles have also been glitched.  Misuse of the core happens and compensations result.  Holding in the abdominals also increases pressure in the system: upward toward the diaphragm or downward toward the pelvic floor.  These pressures and tensions can affect digestion/GERD, menstruation, organ prolapse, abdominal wall separation/hernias.
• Barely breathing:  Many people breathe shallow, with minimal diaphragm movement and mostly upper chest and neck movement.  This does not allow for the natural active range of motion that should happen with each breath. On the inhale the diaphragm shortens, pushing downward to make room for the lungs to fill with air.  As the diaphragm shortens, the abdominals and the pelvic floor oppose by lengthening.  Then on the exhale, the abs and pelvic floor shorten and the diaphragm goes back to its resting length.  This movement allows for blood flow, oxygen delivery, optimal muscle function and management of internal pressures.  Shallow breathing can lead to a hyper-ventilatory state which can present as:  increased tension, aches and pains, poor concentration and weird sensations in the body (numb, tingling).

The First Step to Strengthening Core:

The first step to strengthening the core is to move all the parts.  The gif above shows the movement of the deeper canister: diaphragm, pelvic floor and abdominals.  The abs and pelvic floor are opposing the diaphragm during inhale and exhale. Can you feel your pelvic floor move during breathing?  Can you feel your abs move?  You might notice that you can only move your chest at first.  See if you can start to bring awareness into: upper abdominals, then belly button, then lower abdominals, then pelvic floor (typically I have people sense the anus- we are used to holding our sphincter muscles to prevent passing gas.  See if you can let the sphincter go on the inhale, then notice if it lifts back up on the exhale). Don't force or try to take big breaths, just direct your focus.  Allow your breathing to be effortless, inhale/exhale are balanced.   Remember your core cannot be strong unless is can access it's full range of motion.  
Know your core: 1) stop holding your core tight all the time (that includes wearing spanx) and 2) learn how to let your core move during breathing.
