Posterior Tibialis

Posterior Tibialis

Pictured above is the posterior tibialis muscle. It stabilizes your foot & ankle for balance by pulling the bones of your arch toward the back of your lower leg (plantar flexing the ankle) and rotating the bottom of your foot inward (inverting your foot). It attaches underneath all of the muscles attached to the back of your lower leg between the two bones, and its tendon runs down the back inside of your ankle and attaches to most of the bones in the arch of the foot.

If this muscle locks up it will feel tight and possibly painful in the bottom of your foot. This muscle is a BIG contributor plantar fasciitis. Rarely will this muscle lock up without the toe flexor muscles needing attention too. The soleus muscle ALWAYS needs attention if your posterior tibialis muscle locks up, and your peroneal muscles will also likely need some TLC on the outside of your lower leg.

The posterior tibialis muscle is displayed on the right leg. On the left leg the muscles located in the back of your lower leg 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.

Flexor Digitorum Longus

Flexor Digitorum Longus

Pictured above is the flexor digitorum longus muscle. It stabilizes your foot & ankle for balance by pulling all of your toes except the big toe toward the bottom of your foot. If contracted hard enough, it pulls the bottom of your foot toward the back of your lower leg like when you point your toes. It attaches underneath the soleus muscle along most of the back of the bigger of your lower leg bones (the tibia), and its tendon runs down the back inside of your ankle and attaches to the bottom of all the toes except the big toe.

If this muscle locks up it will feel tight and possibly painful along the center portion of the back of your lower leg, and your toes will not move well. This muscle and the flexor hallucis longus are BIG contributors to hammer toes, claw toes, and other general lower leg and foot pains. Rarely will this muscle lock up without the other toe flexor muscle needing attention too (the flexor hallucis longus). The soleus muscle ALWAYS needs attention if your flexor muscles are locked up, and your toe extensors will also likely need some TLC on the front of your lower leg deeper than the anterior tibialis.

The flexor digitorum longus muscle is displayed on the right leg. On the left leg the muscles located in the back of your lower leg 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.

Flexor Hallucis Longus

Flexor Hallucis Longus

Pictured above is the flexor hallucis longus muscle (the 'big toe flexor'). It stabilizes your foot & ankle for balance by pulling your big toe toward the bottom of your foot. If contracted hard enough, it pulls the bottom of your foot toward the back of your lower leg like when you point your toes. It attaches underneath the soleus muscle on the lower 2/3 of the back of your lower leg bones moreso on the smaller outer bone (the fibula), and its tendon runs down the back inside of your ankle and attaches to the bottom of only the big toe.

If this muscle locks up it will feel tight and possibly painful along the lower portion of the back of your lower leg, and your big toe will not move well. This muscle and the flexor digitorum longus are BIG contributors to hammer toes, claw toes, and other general lower leg and foot pains. Rarely will this muscle lock up without the other toe flexor muscle needing attention too (the flexor digitorum longus). The soleus muscle ALWAYS needs attention if your flexor muscles are locked up, and your toe extensors will also likely need some TLC on the front of your lower leg deeper than the anterior tibialis.

Extensor Digitorum Longus

Extensor Digitorum Longus

Pictured above is the extensor digitorum longus muscle. It stabilizes your foot & ankle for balance by pulling your toes toward the front of your shin. It attaches underneath the anterior tibialis to the most of the front of your lower leg bone from just below your knee, and its tendons run down the front of your ankle and attaches to all of the toes except the big toe.

If this muscle locks up it will feel tight and possibly painful along the front of your lower leg, and your toes will not move well. This muscle and the extensor hallucis longus are BIG contributors to shin splints, hammer toes, claw toes, and other shin and foot pains. Rarely will this muscle lock up without the other toe extensor muscle needing attention too (the extensor hallucis longus). The soleus muscle ALWAYS needs attention if your extensor muscles are locked up, and your toe flexors will also likely need some TLC on the back of your lower leg deeper than the soleus.

Peroneus Brevis

Peroneus Brevis

Pictured above is the peroneus brevis muscle. It stabilizes your foot & ankle for balance by pulling the back of the bones that lead to your pinky toe toward your outer ankle bone (everts your foot). It attaches to the lower 1/3 of the outside of your lower leg bone and its tendon runs behind the outside of your ankle and attaches to the bone on the outside of your foot that leads to your pinky toe.

If this muscle locks up your ankle will feel tight and possibly painful along the backside of your ankle and the bottom 1/3 of the outside of your lower leg. Rarely will this muscle lock up without the peroneus longus needing attention too. The soleus muscle ALWAYS needs attention if either of your peroneal muscles are locked up.

Peroneus Longus

Peroneus Longus

Pictured above is the peroneus longus muscle. It stabilizes your foot & ankle for balance by rotating your foot outward (everting your foot) and pulling the pinky-side of your foot toward your outer ankle bone. It attaches to the upper 2/3 of the outside of your lower leg bone from just below your knee, and its tendon runs down the outside of your ankle and attaches to many of the bones in the arch of the foot.

If this muscle locks up it will feel tight and possibly painful along the outside of your lower leg. Rarely will this muscle lock up without the peroneus brevis needing attention too. The soleus muscle ALWAYS needs attention if either of your peroneal muscles are locked up.

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.

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.

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.

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.
