Is there a way to specifically target and reduce belly fat?

Walking 10,000 steps every day.

I've been running and consistently climbing stairs, and I've lost some weight. But the stubborn belly fat from my old intestines doesn't seem to budge at all.

Do you know the feeling of walking with your stomach clenched?

If you're not careful for a moment, it shows up, haha. Of course, I've lost weight, so my belly fat has also decreased, but I don't really like how the size has changed. These days, I see things like liposuction and fat-dissolving injections, but I want to lose it through exercise. Is there anywhere in Seoul that can really push me hard with exercise or provide some kind of treatment (??)? I welcome places that can inform me while giving a bit of human dignity-mocking treatment.
