Stomach vacuums train your transverse abdominal muscles. These are not the sixpack muscles but something like a corset all over your belly and therefore they give your core stability. You can easily try it daily. Just suck in your belly and hold it for 30s or suck it in and then release throughout a minute or something like that

My mother encouraged me to do this when I was very young, and I stayed a lot thinner that way compared to my peers. I love her for that!

I'm assuming it's this

There’s more technique involved than sucking your tummy in.
Vacuums are a breathing exercise, you have to completely empty your lungs and stomach until you feel your diaphragm “plug” and then the negative pressure will lift your organs for a lack of a better description. Posture is extremely important to avoid involving the wrong muscle group and to take care of your spine. You also need to do them 3 hours after you’ve eaten so usually they’re best first thing in the morning.
There’s a lot of postures to try from beginner to advanced so I highly encourage anyone wanting to do them to do a lot of research first, don’t just hold your tummy in you have to create negative pressure within your core to do it properly otherwise you risk increasing said abdominal pressure and blowing your pelvic floor muscles out, I received training from a PT I advise anyone interested to get some coaching if you can afford it
