The Study
The Effects of Functional Magnetic Stimulation on Rectus Abdominis Muscle Size and Abdominal Subcutaneous Adipose Tissue Thickness
This study watched 10 people use a special machine on their stomachs and saw that their muscles got a little bigger and their belly fat got a little smaller. But because no one else was compared, we don’t know if the machine caused it — maybe they ate better or moved more without saying so.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
A machine uses magnetic pulses to make your stomach muscles contract really hard, like doing tons of crunches in minutes.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — you can get a tighter, more defined stomach without losing weight, which might help people who are already lean but want better muscle definition.
- 2After 10 sessions, stomach muscles got thicker by about 6 mm, fat under the skin got thinner by about 4 mm, and waist got 2.76 cm smaller — but weight didn't change.

To see abdominal muscles, a person needs to have a low enough level of fat over the abdomen and enough muscle mass in the rectus abdominis.
A treatment using magnetic pulses on the abdomen for three weeks did not cause weight loss in healthy adults, but it did reduce waist size and fat thickness in the area, suggesting the effect stayed local and did not affect overall body weight.
Healthy adults who received 10 sessions of functional magnetic stimulation reported feeling more satisfied with how their abdomen looked and stronger in their muscles, even though their weight did not change significantly.
A non-invasive technique using magnetic stimulation on the abdomen, applied over three weeks, was associated with an increase in abdominal muscle thickness and a decrease in underlying fat thickness in healthy adults, without major changes in overall body weight.
A non-invasive abdominal stimulation technique used over three weeks did not cause people to lose weight, meaning any reduction in waist size or fat thickness was not caused by losing overall body weight.
In healthy adults, receiving 10 sessions of abdominal functional magnetic stimulation over three weeks did not result in any serious side effects, suggesting it is safe in the short term.
