Introduction

This video explains the anatomy of the calf muscles, focusing on the often-overlooked soleus muscle. The speaker, a medical student, reveals how understanding the different origins and insertions of the gastrocnemius and soleus muscles allows for more effective calf training.

Key Takeaways

• The calf muscles consist of two main muscles: the gastrocnemius (responsible for definition) and the soleus (responsible for volume).
• Both muscles insert on the calcaneus (heel bone) and plantar flex the foot.
• The gastrocnemius also flexes the knee joint, while the soleus does not.
• Working calves with a locked knee primarily engages the gastrocnemius.
• Flexing the knee reduces the gastrocnemius's involvement, allowing the soleus to be worked more effectively.
• To fully develop calf muscles, exercises should be performed with both a flexed and locked knee.
