🧠Muscle of the Day: Adductor Magnus
In a deep squat, your glutes and hamstrings are at a mechanical disadvantage. This is where the adductor magnus shines. It becomes the primary muscle to initiate hip extension from the bottom of a squat. If you’ve ever felt "inner thigh" soreness after a heavy leg day, you’ve met your adductor magnus. Adductor Magnus - Physiopedia adductor magnus muscle
- The adductor magnus has a dual innervation pattern—obturator nerve for the adductor part and sciatic (tibial) for the hamstring part—so isolated deficits can help localize nerve injury.
- Because of its ischial tuberosity origin, proximal hamstring-like injuries can involve the adductor magnus; consider both when evaluating posterior-medial thigh/ischial pain.
- Rehabilitation should address both adduction strength and hip extension/pelvic stability for optimal functional recovery.
- Have the patient lie prone (face down) with the knee slightly bent.
- Locate the ischial tuberosity (the "sit bone").
- Slide your fingers distally and laterally toward the medial femur.
- Ask the patient to adduct the leg against resistance. You will feel the thick, rope-like belly of the muscle contract.
A Unique Feature: The Adductor Hiatus
Hip Extension:
The hamstring portion assists the glutes and true hamstrings in extending the hip, particularly when the leg is in a flexed position (e.g., coming up from a deep squat). Caption Option 1 (Educational & Detailed) 🧠Muscle
The adductor magnus is unique because it is a "hybrid" or "composite" muscle. It is so large that it is divided into two distinct parts, each with its own nerve supply and function: Have the patient lie prone (face down) with
