Innervated by the posterior branch of the obturator nerve , this portion is primarily responsible for adduction.
The anterior adductor portion assists in internal rotation of the thigh.

Since the nerve passes near the muscle, tightness or hypertrophy (excessive growth) can occasionally lead to nerve entrapment, causing pain or numbness in the inner thigh. 5. Training and Maintenance
Its fibers insert along the entire length of the linea aspera on the posterior surface of the femur and the adductor tubercle . Structure and Functional Divisions
Given its size and heavy workload during high-velocity movements, the adductor magnus is frequently implicated in sports injuries and chronic pain syndromes. Adductor Strains ("Groin Pulls") | Feature | Description | | :--- |
