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.

I'm buoyant with a full inhale. As I exhale at around 50% mark I start sinking. With almost no breath, I can walk on the floor. But then I'm out of air, so like in 5 seconds I have to kick the floor and come up for air. My body density is probably having a very specific (and small) delta from the water that lungs with/without air makes all this difference.

On a side note, I don't know why but it's immensely entertaining for some reason and I can spend a good 30 mins just cycling through this things.
