Welcome (back). So far I've presented a basic definition of ideal posture, mechanisms of how we move away from it and a set of movements designed to help re-educate those with rounded shoulders and an overached lower back towards something more ideal for them.
That last part of this series while helpful will be made much more powerful by what follows.
Posture is a very useful and very limited concept.
Sometimes we stand still in a resting 'neutral' position that we refer to as posture. It is a very clear indicator of the state of balance of muscular recruitment throughout a person but we primarily care about muscular recruitment patterns because they inform us about how well a person will be able to move.
Rounded shoulders, for example, usually mean a person will struggle to properly reach overhead and bend backwards comfortably.
Analysing and improving posture, for me at least, is just a means of improving your ability to move.
It is movement that will matter to you in everyday life and in your sport..
and it is through moving that you will move better.
Movement will be your best postural medicine and will fuel better performance.
To become accustomed with what your joints can do, maybe through some anatomy reading or coming to something like the course I'm running next February, and then to move them in such a manner will over time lead to better static posture too.
Move in every direction you can. Fold. Extend. Rotate. Bend to the sides. Go slowly and quickly. Hold positions throughout your ranges, especially near the end ranges where you are unaccustomed to holding.
Combining the movements based around the resting position from part 3 of this series with upgrading the movement of all of your joints through whatever ranges you can do will serve you well in your movement towards better static posture.
