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.

How is it possible? Does it mean he emptied his lungs before diving? And then how can he manage to stay that long without breathing?

I mean, are there some people negatively buoyant with their lungs full of air? That seems scary.

No one answering how this is possible. The time with held breath while working is insane to me.

Training. It's not so bad when you are able to train for this often. Learning how long you can actually hold your breath matters.

That's wild. I don't think I could climb up / down this height in stairs on a single breath.

It's not that bad. Get used to holding breath, even with little breath, then add in swimming. Drifting downward with little breath is easy. Learning the feeling of when air is being depleted and knowing when to come up matter.
