The remarkable Soleus muscle. Located in the back of the lower leg, attaching to the Achilles tendon and the heel is the Soleus muscle. The Soleus is a remarkable muscle generally known for its resilient endurance and contractile strength.
The soleus muscle (as well as other muscles) holds up the body when standing to maintain the centre of mass and prevent us face-planting forward. As the soleus fatigues or stiffens, gait changes, the Achilles loads differently, and calf tightness shows up — often far from where the problem started.
