According to AZ Central, hula hooping works the entire abdominal region, including the rectus abdominus, external obliques, internal obliques and transversus abdominus. Hula hooping is also a good aerobic exercise.
Hula hooping is an effective workout because it strengthens and tones the abs as the body moves to keep the hoop spinning, says AZ Central. It has the added benefit of increasing concentration, as it takes a large amount of focus to keep the hoop in rotation. It also increases stamina and aids in relaxation; the repetitive motions can be soothing and even act as a meditative tool. As it is an aerobic exercise that burns calories, hula hooping also helps with weight loss.
