The Vastus Lateralis is one of the four muscles that make up the quadriceps group, located on the outer side of the thigh. It plays a crucial role in extending the knee and stabilizing the patella during movement. This muscle is particularly important for activities such as running, jumping, and squatting. As part of the quadriceps, the Vastus Lateralis works alongside the Vastus Medialis, Vastus Intermedius, and Rectus Femoris. Strengthening this muscle can enhance athletic performance and reduce the risk of knee injuries. Exercises like squats and leg presses effectively target the Vastus Lateralis.
