10. The Deep Front Line

     The Deep Front Line is the body's myofascial core, as it defines the deep three-dimensional space deep within the body.  It's main postural function is providing support and lift in the inner arch of the foot, stabilizing both segments of each leg, as well as the hips, supporting the lumbar spine from the front, giving shape to the abdominopelvic balloon, stabilizing the chest while allowing the expansion and relaxation of breathing, and balancing the neck and head. 

     If this line is lacking definition, strength, and/or proper balance, there is an overall shortening throughout the body, which encourages collapse of the pelvic and spinal core, laying the groundwork for postural deviations in all the other meridians.

The Deep Front Line can be broken down into six parts:

Lowest Common

Lower Posterior

Lower Anterior

Upper Posterior

Upper Middle

Upper Anterior

So, I've broken down each list below accordingly.

Muscles of the DFL:

Lowest Common:

Pericardium

Mediastinum

Scalene muscles

Upper Anterior:

Pilates is a great way to engage this line properly, therefore setting the foundation for all the other lines to function at their best.

Here's a great video that shows a lunge stretch for the DFL:

And that's it!

I'll be back the week of the 22nd with a new topic and great tips on pain relief and healthy living.

Be good to yourselves. <3
