Plantaris

Plantaris
Pictured above is the plantaris muscle. It helps bend your knee and raises your heel toward your knee. It attaches to the inside portion of the back of your thigh bone very near your knee and to the back of your heel bone. If this muscle locks up it will feel like a tight ball behind the knee. It is typically a symptom muscle instead of a source of your troubles. If you have plantaris issues you have OTHER bigger and stronger muscles that are not doing their job properly.

If this muscle regularly locks up on you, then you need to work on your quads EVERY DAY. Your quads extend (straighten) your knee, and the plantaris helps flex your knee. The quads are MUCH stronger than the plantaris (and all the other knee flexors, for that matter). In addition, your soleus muscle is probably locked up and your brain is firing the plantaris to help raise your heel more than it can handle. Be sure you check the soleus to relieve knots in it so your plantaris is no longer working harder than it should be.

The plantaris is displayed on the right leg. On the left leg 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.

Popliteus

Popliteus

Pictured above is the popliteus muscle. It unlocks and bends your knee. It attaches to the outer portion of the back of your thigh bone very near your knee and to the upper portion of the inside rear of your largest lower leg bone (the tibia). If this muscle locks up it will feel like a tight ball behind the knee.

If this muscle regularly locks up on you, then you need to work on your quads EVERY DAY. Your quads extend (straighten) your knee, and the popliteus flexes your knee. The quads are MUCH stronger than the popliteus (and all the other knee flexors, for that matter). Be sure you check the other muscles that attach to the knee when dealing with popliteus trouble.

Gastrocnemius

Gastrocnemius


Pictured above is the gastrocnemius muscle. It pulls your heel toward your thigh and also flexes your knee. It attaches to the back of your thigh bone very near your knee and to the upper portion of the outside of your Achilles tendon. Your soleus muscle also attaches to the Achilles tendon, but on the inside (the other side that the gastroc attaches to). Your soleus muscle is VERY likely to need LOTS of stretching and SMR attention. Occasionally, the gastroc will need attention too.

Gluteus Minimus

Gluteus Minimus

Pictured above is the gluteus minimus muscle. It primarily works to extend (open) the hip. However, it has a small portion of muscle fibers that cross in front of the hip, so it can work as a weak hip flexor, too. If this muscle is overly tight then it is EXTREMELY LIKELY that you need to address the rectus femoris and the psoas (in that order).

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 individual muscle detail for all the other muscles in the body with our Coach membership.

Gluteus Medius

glute med -- 2016
Gluteus Medius

Pectineus

pectineus -- 2016
Pectineus

Pictured above is the pectineus muscle. It is nick-named the "4th adductor" muscle and it pulls the thigh toward the pubic bone. When this muscle is overly tight (and this is true for many of us), you will have trouble comfortably opening your legs really wide. This leads to compromised leg positioning for some functional movements such as the deep squat.

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.

Gracilis

Gracilis

Pictured above is the gracilis muscle. It runs from your pubic bone to just below your knee on the inside of your leg. It primarily works as a stabilizer for the leg on the hip joint and pulls the leg inward. When this muscle is overly tight (and this is true for many of us), you will have trouble comfortably opening your legs really wide. This leads to compromised leg positioning for some functional movements such as the deep squat.

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.

Tensor Fasciae Latae

tfl -- 2016
Tensor Fasciae Latae

Pictured above is the tensor fasciae latae. It primarily acts on the IT Band and keeps the knee from drifting inward. It is also a weak hip flexor muscle. You can't move your hip in any direction without using this muscle. Cyclists, speed skaters and other athletes that spend large amounts of time actively using their hip in a flexed position 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 and rectus femoris for excessive tension you are missing the most significant inhibitors of proper back function.
