What actions do both gluteus maximus and hamstrings assist with?

The gluteus maximus and hamstrings are both crucial muscles involved in hip extension, which is the primary action they assist with. The gluteus maximus is the largest muscle in the buttocks and is the main powerhouse for extending the hip, particularly during activities such as standing up from a sitting position, climbing stairs, or running. The hamstrings, located at the back of the thigh, also contribute to this movement by assisting in the extension of the hip joint, especially when the knee is flexed, such as during activities that require the leg to move behind the body.

Both of these muscle groups are essential for functional movements that involve hip extension, allowing for effective propulsion and stabilization during dynamic activities. Their coordinated action is particularly important in athletic performance and activities of daily living where powerful hip extension is necessary.
