The adductor muscle group is composed of several muscles that allow for inward movement of the hip. These muscles are responsible for bringing the legs together when we walk, run or perform any other physical activity. Some of the synonyms for adductor muscles are groin muscles, inner thigh muscles, and adductors. The primary adductor muscles include the adductor brevis, adductor longus, adductor magnus, pectineus, and gracilis. These muscles work in harmony with the surrounding muscles to help you maintain balance and stability. It is essential to keep these muscles strong as they play a significant role in supporting the hip joint and preventing injury.
