Let’s all look at our groins today A group of muscles called the adductors make up the area of the inner thigh known as the groin. These muscles bring the leg toward the center of the body, as in crossing one leg in front of the other. They are also stabilizers for sitting and standing. Too-tight or too-weak adductors can lead to hip or lower back pain. Try this stretch and squeeze a pillow to warm and awaken those adductors.
