Answer:
Quadriceps
Step-by-step explanation:
The meniscus isn't muscle, it is the cartilage in your knee.
The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They flex the knee joint and extend the thigh to the backside of the body. They are used in walking, running, and many other physical activities.
Although the hamstrings do help in everyday walking, the quadriceps are the primary muscles involved in walking because they are the muscles of the lower leg, thigh and knee.
