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.

Hip Flexors

hip flexors -- 2016
Hip Flexors


Pictured above are the hip flexor muscles. All of them pull your leg up toward your spine, and one of them pulls your spine toward your leg (like when you sit up). They are BY FAR the most influential group of muscles in the body. You can't move your hip or lower back in any direction without using one or more of these muscles. 80% of all adults over 18 years of age have some form of back pain. If you aren't checking your hip flexors for excessive tension you are missing the most significant group of muscles that contribute 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. On the left side you can see the other muscles that are present in the same area as the hip flexors, and a couple muscles that act as mild hip flexors (Tensor Fasciae Latae & Sartorius).

Psoas

Psoas

Pictured above is the psoas. It is one of the hip flexor muscles, and pulls your leg up toward your spine (like when you lift your leg), or your spine toward your leg (like when you sit up). It is BY FAR the most influential muscle in the body. 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.

Rectus Femoris

rf -- 2016
Rectus Femoris

Pictured above is the most influential of the quadriceps, the rectus femoris. The leg on the right has the rectus femoris labeled. This is the only quadriceps that acts on the 2 largest joints in your body - the hip AND the knee. If this muscle goes dysfunctional with too many muscular knots, then all movements involving either of these two joints will be compromised. If you only have time for one SMR exercise, DO SMR FOR THE RECTUS FEMORIS! (It is that important.)

The leg on the left has all the muscles that cross your thigh in the region of the rectus femoris. All of the muscles in the left leg are see-through so that you can appreciate the location and size of each muscle relative to the others.
