A post to help explain the key muscles to my Base-Line Hypothesis of Human Health and Movement.

Anatomy is wordy and it's easy to get lost but knowing the details isn't important:

Keep thinking about these 5 (paired - left and right) 'main muscles of moment' and how you use them as you move through your daily life. Get to know how your body feels.

1. Rectus femoris

Below the knee, feel for the lump at the front of your shin bone (tibia). Run your hands up over your kneecaps and front of your thighs to just below the sticking-out bone at the front of your pelvis (hip bone). This is the full extent of the rectus femoris muscle.

The rectus femoris muscles align the hip and knee joints.

A muscle sandwiched between layers of tough connective tissue.

From shin - a ligament that contains the kneecap turning into a layer of connective tissue at the back of the muscle.

From hip - short ropes of tendon from hip bone turning into a layer of connective tissue down the front of the rectus femoris muscles.


2. Gluteus maximus.

The largest skeletal muscles of the body (covering a lot of complicated anatomy prone to pain/injury).

Hands on buttocks - feel for the muscles contracting. "Buns of steel".

The gluteus maximus works in tandem with the rectus femoris, stabilising the legs through a full range of natural movement - when connected to Base-Line support.


Now the key muscles to connecting mind to muscles, body to brain ...

The body's 'core pillar of strength' ...

Your 'Base-Line':

3. Pelvic floor. BASE

The pelvic floor - a basket of muscles within the bones of the pelvis.


Several small muscles spanning the pelvic canal. Left and right sides a mirror image.

The pelvic floor - a crescent shape on the body's midline.


These muscles are the base foundation for the body.

Closely associated with the anus and genitals.

Kegel exercises are the most well-known introduction to strengthening the pelvic floor muscles. Picture these muscles contracting in your mind, feel for them working.   Find a connection. Keep working at it.   It will become easier the more you practice.

Aim for a balanced contraction left and right sides. Providing the sensory information for the 'base' point of our 'body map [LW · GW] in the mind' from where the rest of the body extends.

[I get the impression that the pelvic floor is generally accepted to correspond to the "root chakra [LW · GW]".]

The pelvic floor muscles. The base of the body.

4. Rectus abdominis. LINE

"The abs" = rectus abdominis muscles.

Strong and powerful, the muscles that allow the body to bend and flex in all directions when functioning at optimal.

Think of these muscles as your central LINE, extending from a solid Base, that should be free to move and fully extendable.

The rectus abdominis muscles:


Place your hands over the muscles, starting from the bone between your legs (pubic symphysis) then, as you breathe in, move your hands up thinking of activating and elongating - section by section - all the way up to your chest. Repeat to lengthen the muscles as much as you can.

Think of the panels of muscle as a set of lights to be activated in sequence. Or whatever works for you ...

Find the first 3 markers in the body alignment game [LW · GW] with your Base-Line muscles.

The rectus abdominis muscles - our core pillar of strength.

Breathe with your Base-Line. Think stronger and longer with every breathe in.

5. Trapezius

A blanket of muscle that should be smooth and wrinkle-free.


The trapezius muscles can be thought of as 6 sections (approximating - 2 triangles and a horizontal strip to the shoulders on each side as shown above).



Movement of the upper body should begin from the lower trapezius.

Like wings extending from the middle of your back.

Think of lifting your shoulders from below, rather than pulling them up.

The trapezius muscles meet midline and merge with the nuchal/supraspinous ligaments [LW · GW] - our 'secondary guides for alignment'.

The trapezius muscles - guiding and supporting the head and arms through a full range of movement and aligning the upper body.


Working Towards Body Alignment & Balance:


Imagine a ribbon from pubic symphysis of your pelvis:


To the external occipital protuberance (midline bump) at the back of your skull:

It should be possible to fully extend the ribbon where our midline anatomy is 'aligned'.

This is possible when the body has a full range of movement and is functioning at optimum. Body alignment and balance. [LW · GW]


EVERYTHING STARTS FROM YOUR BASE-LINE.

Working with Base-Line (pelvic floor rectus abdominis) muscles gives us a connection to sensing the position of our linea alba [LW · GW] ("white line" in Latin).

The linea alba - our primary guide for body alignment.

Feel for the anatomical markers associated with the linea alba:

1. Pubic symphysis (home of the clitoris/suspensory ligament of the penis).

2. Navel (belly button).

3. Xiphoid process - midline "⋏" at the bottom of breastbone (sternum).


Can these 3 midline markers form a straight line?

As far apart as possible?

How does that feel? Take a break and play the body alignment game [LW · GW].

BODY ALIGNMENT with the main muscles of movement:



Find your 5 main muscles and work towards regaining a full range of natural movement, releasing the physical tensions on your body. The key to better health.
