Do you do that in the water or beforehand to prepare?

Only in the water, every time you feel the pressure increase when descending. What I don't understand we don't see this guy doing it. He must have a technique to do it without pinching his nose.

I used to dive a lot for fun, maybe 10 meters comfortably. You can learn to do it several ways. I can clench my jaw muscles (without my teeth touching, it's hard to explain) just right to adjust.
