What Is a Soleus Stretch?
A soleus stretch is any exercise intended to increase flexibility in the soleus muscle, which is a muscle in the calf. Found underneath the gastrocnemius, the large two-headed muscle that is visible when flexing the calf, the soleus is a slightly smaller muscle that originates below the knee on both the tibia and fibula bones and runs vertically downward, attaching via the Achilles tendon to the heel bone. Because it shares the Achilles with the gastrocnemius, these two muscles often work synergistically during lower leg movements.
