Its main job is to bring the leg toward the midline of the body (adduction). It also assists in hip flexion.

The Adductor Magnus is the largest and deepest muscle of the group. It is a anatomical beast—a thick, powerful sheet of muscle that is actually composed of two distinct parts with different functions.

Though they work together as a team, the and Adductor Magnus have distinct anatomies and functions. Understanding the difference is key to unlocking hip strength and rehabilitating groin injuries.

Weak adductors are a primary cause of knee valgus (knees caving inward) during squats and landing, leading to ACL injuries. Strengthening these muscles is vital for structural balance.

Helps extend the hip (pulling the leg backward), much like the hamstrings.

As the name suggests, the adductor magnus is the largest and most complex muscle in the medial compartment. It is so massive that it is often called the "fourth hamstring."
