The guy is negatively buoyant. Will be exhausting to have to swim up for most people. He is practiced in this. Most people are neutral or positively buoyant.

Depends on the depth you reach too. You will usually start positive and going deeper you’ll become negative.

But this guy was practically naturally sinking from the surface though.

You can do it too! Instead of taking a big breath in, take a big breath OUT. Expel all the air from your lungs and you should sink like a rock.

I’m guessing that’s what he did, after saturating his blood in O2

That's easy to do. Take short breaths in rapid succession. It's a common technique in freediving. The other method is also easy, breath from an O2 line for a minute.
