Adductor Magnus Muscle 'link'

Everyone stretches their groin with "the butterfly." That stretches the short adductors. To stretch the Adductor Magnus (specifically the long, hamstring-like fibers), you need a different approach:

Take a squat stance wider than shoulder-width. As you squat down, shift your weight to one side (Cossack squat). You will feel an immediate stretch and contraction in the adductor magnus of the straight leg.

In strength training, we talk about the "posterior chain" (glutes, hamstrings, erectors). The Adductor Magnus is frequently referred to in biomechanics papers as the fourth hamstring . adductor magnus muscle

This is the isometric killer. Lie on your side, place your top leg on a bench, and lift your hips off the ground using your bottom leg's adductors.

Trigger points in the Adductor Magnus can mimic other serious conditions. Everyone stretches their groin with "the butterfly

As you descend into a squat, the adductor magnus prevents your knees from caving inward (valgus collapse). It keeps the femur in a neutral alignment relative to the pelvis.

Because the hamstring part of the AM attaches to the adductor tubercle on the femur (near the knee), it maintains a consistent moment arm (leverage) throughout the squat. When your hamstrings "turn off" in the hole of a squat, the Adductor Magnus is working overtime to extend your hip. You will feel an immediate stretch and contraction

Pro tip: Focus on driving your knees out toward your elbows on the way up.
