For years, ab machines, crunch challenges, and "belly fat workouts" became a billion-dollar industry.
The promise was simple:
Do enough sit-ups... and your belly fat will disappear.
It sounds logical.

If you work your abs, shouldn't the fat above them burn away?

But researchers tested exactly that.
In one well-known study, participants performed abdominal exercises for weeks. Their abdominal muscles became stronger—but they did not lose more belly fat than elsewhere on the body.

Why?

Because your body decides where it loses fat based on genetics, hormones, and overall energy balance—not on which muscle you're exercising.
That's why visible abs are mostly the result of lower overall body-fat percentage, built through consistent nutrition, strength training, and time.
Crunches strengthen your abs.
They don't selectively melt the fat covering them.

Highlight this conclusion:

"Abdominal exercise alone was not sufficient to reduce abdominal subcutaneous fat."
