The hip joint has less freedom of movement than the shoulder joint because the articulating parts of the hip are closer together than those of the shoulder. The joint capsule of the hip is surrounded by muscles and the hip has more supportive ligaments than the shoulder, but these factors do not necessarily limit the range of motion as much as the close proximity of the hip bones. The hip joint capsule may also be less elastic than the shoulder capsule, but this is not the main reason for the difference in range of motion.
