What muscles are involved in walking?

Walking can actually be considered a full body exercise. Although the locomotion comes from the work the legs are doing, the arms still have to swing, and the core still has to work to stabilize you while you’re moving. The primary muscles involved in walking are the muscles of the lower leg (soleus, gastrocnemius, tibialis anterior/posterior, and peroneals), and the thigh/knee (vastus lateralis, medialis, obliques, and rectus femoris).
