Helena peered at the muscle. No electrical stimulus had been applied. She leaned closer. Etched faintly into the connective tissue of the hamstring portion were words—not scar tissue, but what looked like tiny, deliberate script. She pulled out a magnifying loupe.
Unlike the true hamstrings, which can influence internal or external rotation of the knee, the hamstring portion of the adductor magnus acts primarily in the sagittal plane. This makes it a "pure" hip extensor that helps stabilize the pelvis during heavy compound movements. 3. The "Fourth Hamstring" hamstring portion of adductor magnus
