Which muscle extends the hip and laterally rotates the hip?

The gluteus maximus is the primary muscle responsible for extending the hip and laterally rotating it. This muscle plays a crucial role in various movements, particularly those involving activities like running, cycling, and climbing stairs. Its position and orientation enable it to effectively extend the thigh at the hip joint, working to move the leg backward and stabilize the pelvis during movement.

In addition to its extension capability, the gluteus maximus also contributes to lateral rotation of the hip, which is essential for various athletic movements and maintaining proper alignment of the lower body during functional activities. Its dual role in hip extension and lateral rotation makes it a powerful muscle in the posterior chain, which is vital for overall lower body strength and stability.
