Instructor: Joshua Bowles

Joshua is a Sports Medicine and Athletic Training Instructor and has a Master's degree in Kinesiology.

In this lesson we will discuss the muscles that make up the Adductor muscle group. Specifically we will cover the Adductor Magnus, Adductor Brevis and the Adductor Longus and describe the function and location of these important muscles.

Powerful Movers

Muscles in the leg are generally known for being a powerful aspect of the human body. Running, jumping, skiing, playing sports, and even just walking are amazing examples of what the muscles of the lower body make possible. Have you ever stopped to think about the muscles that help you get into your car everyday? Or how about the muscles that help you put on your best dance moves? There are a few muscles that help us in many of these everyday movements that you may not be that familiar with. These are known as the Adductors.


Muscles are usually named for one or more factors including size, shape, location or function. In the case of the Adductor group, they are named for their function. The word adductor comes from the Latin words, ad meaning towards and ducere meaning to lead. The function of the Adductors is primarily the movement of adduction, which involves movement of the body part towards the body itself. In this case, the Adductors are located in the upper leg area attached to the femur, known as the thigh bone. There is an important structure on the inside of the femur that these muscles all attach to known as the linea aspera. These muscles help to bring the femur closer to the center of the body and help to stabilize the leg in a position close to the midline of the body. These muscles also play a role in hip flexion, meaning they help to bring the femur up towards the stomach.

Adductor Magnus

The three types of Adductors are named for their size and the Adductor Magnus is the largest of this group. The term magnus means large in size in Latin. Shaped somewhat similar to a triangle, this muscle originates in the pelvic region on the ischial tuberosity which is a large bony projection on the Ischium, one of the three skeletal components of the pelvic girdle. The Adductor Magnus attaches on the top of the femur down to the bottom of the femur close to the knee. The primary function of this muscle is adduction and hip flexion. It plays a vital role in walking, running, jumping and everyday leg stabilization.
