Description
1 study reviewed
In plain English

Obese postmenopausal women who did either high-intensity interval training or resistance training three times a week for four weeks experienced measurable decreases in body mass index, waist circumference, and waist-to-hip ratio.

See the scientific wording

Four weeks of either high-intensity interval training or resistance training three times per week leads to statistically significant within-group reductions in body mass index, waist circumference, and waist-to-hip ratio in obese postmenopausal women, suggesting both modalities can improve body composition in the short term.

Why this might work

When the body works hard during exercise, it burns more calories and breaks down stored fat for energy, which makes the body lighter and reduces fat around the waist and hips.

  1. Study: The Effect of High Intensity Interval Training and Resistance Training in Altering Body Composition of Obese Postmenopausal Women

    In this study, obese women after menopause did either intense short bursts of exercise or weight training three times a week for four weeks—and both groups lost belly fat and got a little lighter. So yes, either kind of workout worked.
