Serratus Posterior Inferior

spi -- 2016
Serratus Posterior Inferior

Pictured above is the serratus posterior inferior (SPI). It is an important muscle to address because it tends to be tight and limit your ability to draw in a deep breath.

It is commonly overstretched and lacking proper mobility in persons with poor posture due to excessive rounding of the middle and lower back. 80% of all adults over 18 years of age have some form of back pain. If you aren't checking the SPI for excessive stiffness you are missing one of the most significant links to proper back function.

The muscles on the left are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.

Iliopsoas Roll

iliopsoas-roll-1a--gallery
8th Secondary -- Iliopsoas Roll
Use this SMR exercise AFTER the Quads Roll

This SMR exercise is a variation of the Psoas Press and Iliacus Press techniques to address the Psoas muscle and Iliacus in the Hip Flexors in the front of your hips & core. You may find this exercise easier.

If the Psoas Press or Iliacus Press are too intense to work with then practice the Iliopsoas Roll to more gently work out the "junk" in the front of your hips. It may take a month or two to help your muscles along to become healthy enough to handle the other two techniques (which are the preferred deep tissue SMR techniques for the iliopsoas group).

If you have tightness or discomfort of the hip, knee, or lower back, then this exercise is likely to help.

Transverse Abdominus

Transverse Abdominus

Pictured above is the transverse abdominus muscle. It tightens the space between your ribs and hips and flattens your belly. It works with the other core muscles primarily to stabilize the abdominal region and hold your spine steady while you move your body or lift something. You are not as likely to need to stretch and practice SMR on the transverse abdominus as the oblique muscles. However, be sure to check the PSOAS in particular, as it is EXTREMELY LIKELY to have knots that need attention.

The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others. You can access detail for all the muscles in the body with our Coach membership.

Internal Abdominal Oblique

int oblique -- 2016
Internal Oblique - front


int oblique back -- 2016
Internal Oblique - back

Pictured above is the internal oblique muscle. It twists your torso and pulls your ribs toward the top of the back of your hip bone. It works with the other core muscles primarily to stabilize the abdominal region and hold your spine steady while you move your body or lift something. You will likely need to stretch and practice SMR on the internal oblique on the back of your body on the side you most often twists TOWARDS. Additionally, be sure to check the PSOAS in particular, as it is EXTREMELY LIKELY to have knots that need attention.

External Abdominal Oblique

ext oblique -- 2016

Pictured above is the external oblique muscle. It twists your torso and pulls your ribs toward the top of the front of your hip bone. It works with the other core muscles primarily to stabilize the abdominal region and hold your spine steady while you move your body or lift something. You will likely need to stretch and practice SMR on the deeper internal obliques, but occasionally you may need to focus on the external obliques. Be sure to check the PSOAS in particular, as it is EXTREMELY LIKELY to have knots that need attention.

Rectus Abdominus

abs -- 2016
Rectus Abdominus (the 6-pack)


Pictured above is the rectus abdominus muscle. It is the "6-pack" muscle that pulls your ribs toward your pelvis. It works with the other core muscles primarily to stabilize the abdominal region and hold your spine steady while you move your body or lift something. You will rarely have muscular knots in this particular muscle. However, you will likely need to stretch and practice SMR on the deeper internal or external obliques or the hip flexor muscles. Be sure to check the PSOAS in particular, as it is EXTREMELY LIKELY to have knots that need attention.

The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.

Quadratus Lumborum

ql -- 2016
Quadratus Lumborum

Pictured above is the quadratus lumborum (QL). It is one of the deepest of the lower back stabilizers and it hikes your hip (pulls your hip up toward your spine).

It is commonly too tight in persons diagnosed with one leg longer than the other. You can't move your hip or lower back in any direction without using this muscle. 80% of all adults over 18 years of age have some form of back pain. If you aren't checking the QL for excessive tension you are missing one of the most significant links to proper back function.

The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
