The term "leg muscles" refers to a group of muscles located in the lower extremities, specifically in the legs. These muscles are responsible for various movements and actions such as walking, running, jumping, and other physical activities that require strength and flexibility. Some of the main leg muscles include the quadriceps, hamstrings, calf muscles (gastrocnemius and soleus), and hip adductor muscles. These muscles work together to support and control the movements of the legs, allowing individuals to stand, walk, run or jump with ease.
