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.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyThe 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.
