At first glance the influence of the gluteal muscles on knee health is everything but obvious. However, if you scrutinize the function of the gluteals closely, there will be a big aha-moment. In short, the gluteus maximus and posterior fibers of the gluteus medius are responsible for producing hip external rotation and abduction (moving the leg to the outside as in side-lying leg raise). Both are vital for knee health and here is why.
A healthy hip is very important for efficient movement, since most of the power athletes display is generated at the hip. Jumping, sprinting or deadlifting: without a strong hip you won’t excel at these activities. If we look at posture the hip is just as important, since many times wrong posture can be traced back to adaptations at the hip. It is therefore only logical to start looking for postural problems at the hip, because many other postural issues will improve automatically, as soon as you “fix” the hip.
