The quadriceps, often called the "quads," are a group of four muscles located at the front of the thigh. These muscles play a crucial role in helping us walk, run, and jump by extending the knee. The quadriceps are essential for activities like climbing stairs and squatting, making them important for both athletes and everyday movements. Each of the four muscles in the quadriceps has a specific function, and together they provide strength and stability to the leg. Strengthening the quadriceps can help prevent injuries and improve overall leg performance, which is beneficial for sports like basketball and soccer.
