The calf muscles are located at the back of the lower leg and consist primarily of two main muscles: the gastrocnemius and the soleus. The gastrocnemius is the larger muscle, giving the calf its shape, while the soleus lies underneath it. Together, these muscles play a crucial role in movements such as walking, running, and jumping by helping to lift the heel off the ground. These muscles are also important for maintaining balance and stability during various activities. Strengthening the calf muscles can improve athletic performance and reduce the risk of injuries, making them essential for both everyday movements and sports-related activities.
