The Claim

Resistance training and high-intensity interval training produce equivalent reductions in body mass index in obese postmenopausal women over a four-week period.

In plain English

In obese postmenopausal women, four weeks of resistance training reduces body mass index just as much as four weeks of high-intensity interval training.

See the scientific wording

Resistance training is as effective as high-intensity interval training in reducing body mass index in obese postmenopausal women over a four-week period, despite the common assumption that HIIT is superior for fat loss.

Why this might work

Both types of training cause the body to burn more calories during and after exercise by raising how fast the body uses energy. This increased energy use leads to the same amount of fat loss, even though the exercises feel different.

  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 strength training and intense cardio helped obese postmenopausal women lose body fat over four weeks, but the intense cardio group lost a little more — so it doesn't support the idea that strength training is just as good.
