How does internal rotation of the hips affect glute activation?

Internal rotation of the hips plays a significant role in glute activation, particularly during specific movements. When the hips are internally rotated, it alters the mechanics of the gluteus maximus—specifically how it interacts with the hip joint during activities such as hip extension.

In essence, internal rotation can create a position that is less favorable for optimal glute activation. The gluteus maximus primarily functions to extend, externally rotate, and abduct the hip. When the hip is internally rotated, it moves the muscle out of its most effective range for these functions, leading to decreased activation. Consequently, this reduction in activation is particularly evident during movements that require hip extension, such as squats, lunges, or deadlifts.

Thus, understanding this biomechanical relationship is crucial for developing effective training programs that maximize glute activation. When practitioners focus on positioning the hips properly—avoiding excessive internal rotation—they can ensure better engagement of the glutes during a variety of exercises.
