Introduction

Introduction

The gluteal and pelvic muscles do more than just shape and strengthen the lower body—they play a crucial role in overall function. According to Gray’s Anatomy, these muscles are responsible for much more than hip movement; they serve as the body’s central hub for balance and stability during both everyday activities and athletic performance.

These muscles play a vital role in basic movements like walking, running, jumping, twisting, and quick changes of direction. Additionally, the gluteal muscles and the deep pelvic muscles are key to stabilizing the hip joint, protecting the knees, maintaining proper spinal alignment, and preventing injuries in the lower back and knees.

🔹 According to the classification in Gray’s Anatomy, the pelvic and gluteal muscles are divided into three main groups:

Superficial gluteal muscles: including the gluteus maximus, gluteus medius, and gluteus minimus, which are responsible for hip extension, abduction, and internal rotation.
Deep pelvic muscles: consisting of the piriformis, internal obturator, external obturator, superior and inferior gemellus muscles, and the quadratus femoris, which handle external hip rotation and pelvic stabilization.
Tensor fasciae latae (TFL): which, through the iliotibial band, helps stabilize the knee and control lateral movements of the hip.

From explosive and powerful movements in sports like weightlifting and sprinting to everyday activities such as standing, walking, and sitting, the gluteal and pelvic muscles play a fundamental role in overall body function and health. Weakness in these muscle groups can lead to pelvic imbalances, a higher risk of knee injuries, decreased athletic performance, and chronic lower back pain.

🔹 In this comprehensive review, we’ll analyze the structure, function, and significance of the gluteal and pelvic muscles, as well as explore the most effective ways to strengthen them and prevent injuries.

Gluteal and Pelvic Muscles

1. Superficial Gluteal Muscles

Superficial Gluteal Muscles

Gluteus Maximus Muscle

Gluteus Maximus Muscle

The gluteus maximus is one of the most important and powerful muscles in the body, playing a key role in hip movement, balance, and pelvic stability. It’s essential for strength-based activities like squats, deadlifts, and running, where it drives hip extension and helps maintain pelvic stability.

Gluteus Maximus Muscle

Gluteus Medius Muscle

Gluteus Medius Muscle

The gluteus medius is one of the key muscles in the pelvic region, primarily responsible for hip abduction (moving the thigh away from the body) and stabilizing the pelvis during walking. Weakness in this muscle can lead to issues such as knee pain, pelvic drop, and reduced balance.

Gluteus Medius Muscle

Gluteus Minimus Muscle

Gluteus Minimus Muscle

The gluteus minimus is the smallest and deepest muscle of the gluteal group. Along with the gluteus medius, it plays a crucial role in hip abduction, pelvic stabilization, and internal rotation of the thigh. Weakness in this muscle can reduce pelvic control and lead to issues like imbalance during walking.

Tensor Fasciae Latae (TFL) Muscle

Tensor Fasciae Latae - TFL Muscle

The tensor fasciae latae (TFL) is a small yet powerful muscle located on the lateral side of the hip. It connects to the iliotibial band (IT Band) and plays a crucial role in stabilizing both the pelvis and knee. The TFL is involved in hip abduction, internal rotation, and hip flexion. Weakness or tightness in this muscle can lead to iliotibial band syndrome and knee problems.

3. Deep Gluteal Muscles

Deep Gluteal Muscles

Piriformis Muscle

Piriformis Muscle

The piriformis muscle is one of the deep gluteal muscles located in the posterior pelvis around the hip joint. It plays a key role in externally rotating the thigh, stabilizing the hip joint, and controlling pelvic movement during walking and running. Since the sciatic nerve passes either beside or, in some people, through this muscle, tightness or spasms in the piriformis can lead to Piriformis Syndrome, causing sciatic nerve pain.

Piriformis Muscle

Obturator Internus Muscle

Obturator Internus Muscle

The obturator internus muscle is one of the deep gluteal muscles that plays a key role in externally rotating the thigh and stabilizing the hip joint. Located inside the pelvis, this muscle works alongside other external rotators to maintain pelvic stability and control thigh movements.

Obturator Internus Muscle

Obturator Externus Muscle

Obturator Externus Muscle

The obturator externus muscle is one of the deep pelvic muscles and belongs to the group of external rotators of the thigh. It originates from the external surface of the obturator membrane and surrounding bones, attaching to the trochanteric fossa of the femur. Its main functions are external rotation of the thigh, stabilization of the hip joint, and assisting in pelvic control.

Obturator Externus Muscle

Superior Gemellus Muscle

Superior Gemellus Muscle

The superior gemellus muscle is one of the deep gluteal muscles that, along with other external rotators of the thigh, is responsible for stabilizing the hip joint and externally rotating the thigh. Though small, this powerful muscle plays an important role in controlling pelvic movements and maintaining hip joint stability.

Superior Gemellus Muscle

Inferior Gemellus Muscle

Inferior Gemellus Muscle

The Inferior Gemellus muscle is one of the deep gluteal muscles that, along with other external rotators of the hip, plays a key role in stabilizing the hip joint and rotating the thigh outward. Located just beneath the Superior Gemellus, it works closely with the Internal Obturator and other external rotator muscles to help maintain the strength and stability of the hip joint.

Inferior Gemellus Muscle

Quadratus Femoris Muscle

Quadratus Femoris Muscle

The Quadratus Femoris muscle is one of the deep gluteal muscles belonging to the group of external rotators of the thigh. This short, flat muscle is located at the back of the hip joint and, together with other external rotators like the Superior and Inferior Gemellus, as well as the Internal and External Obturator muscles, plays a crucial role in externally rotating the thigh and stabilizing the hip joint.

Interesting and Practical Facts

1. The gluteus maximus isn’t just about strength!

✔ This muscle is not only the strongest hip extensor but also plays a vital role in maintaining pelvic balance during standing and walking. 🏋️‍♂️

2. The gluteus medius prevents pelvic drop!

✔ If this muscle is weak, the pelvis tilts toward the opposite side while walking—a condition known as the Trendelenburg Sign. 🚶‍♂️
