The Claim

In obese postmenopausal women, performing high-intensity interval training or resistance training three times per week for four weeks is associated with significant reductions in body mass index, waist circumference, and waist-to-hip ratio, with no statistically significant difference between the two exercise modalities for these outcomes.

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, and neither exercise type was more effective than the other.

See the scientific wording

In obese postmenopausal women, both high-intensity interval training and resistance training performed three times per week for four weeks are associated with significant reductions in body mass index, waist circumference, and waist-to-hip ratio, but no statistically significant difference exists between the two exercise modalities in their effects on these outcomes.

Why this might work

When the body is pushed by intense or resistance exercise, it burns more fat for energy and stops storing fat in the belly area, leading to less overall body fat and a smaller waistline.

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

    The study found that both types of exercise helped obese postmenopausal women lose weight and belly fat, but it says HIIT (short bursts of intense exercise) worked a bit better than strength training — so they’re not equally effective, as the claim says.
