Vacuum exercise

Vacuum exercise is when you suck your tummy in and hold it there for a little while. Do you remember when you pretended to be a superhero and tried to make your tummy as flat as possible? That's kind of what it's like.

When you do the vacuum exercise, you're training your muscles to stay strong and tight even when you're not moving around a lot. This can help with things like posture, core strength, and even digestion.

But it's important to remember that vacuum exercise alone won't make your tummy flat, just like how one superpower won't make you a superhero. It's just one part of a healthy lifestyle.
