Sartorius

sarotius -- 2016
Sartorius

Pictured above is the sartorius muscle. It is nick-named the "carpenter's muscle." It primarily works as a stabilizer for the leg on the hip joint and rotates the knee outward. It is also a weak hip flexor. You can't move your hip in any direction without using this muscle. Persons that spend large amounts of time kneeling are likely to need stretching and SMR attention here.

80% of all adults over 18 years of age have some form of back pain. If you aren't also checking the psoas 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.

Iliacus

iliacus -- 2016
Iliacus

Pictured above is the iliacus. It is one of the hip flexor muscles, and pulls your leg up toward your hip (like when you lift your leg). It is one of the most influential muscle in the body. You can't move your hip in any direction without using this muscle. This muscle is VERY LIKELY to need some SMR attention along with the psoas muscle. 80% of all adults over 18 years of age have some form of back pain. If you aren't checking the psoas 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.

Semimembranosis

Semimembranosis

Pictured above is the semimembranosis. It is one of the two internal hamstring muscles that attaches just below the inside of your knee.

The leg on the right has the semimembranosis labeled. The leg on the left displays all the muscles you can address on the back of your thigh in portions of the region of the semimembranosis. 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.

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).

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.

Vastus Intermedius

Vastus Intermedius

Pictured above is the deepest of the quadriceps, the vastus intermedius. The leg on the right has the vastus intermedius labeled. The leg on the left has all the muscles that cross your thigh in the region of the vastus intermedius plus the IT Band. Many people with pain in the IT Band region of their body have tightness in the vastus intermedius muscle and could benefit from releasing that tension. 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.
