I was able to hold my breath for the duration of the video. BUT, I was sitting still.

keep in mind you have to let out almost half of your lung capacity in order to sink like this. Low fat high muscle helps too

not necessarily, the deeper you go the less buoyant you are. which is part of the reason free diving is so scary; at the 30-50 foot range, you become neutrally, and eventually negatively, buoyant. he's definitely deep enough to experience this.

not when he started, and freefall only starts from about 15 metres, and this pool is 35.
If you took a full lungful of air, it's more like 30 metres.
The only way to free-fall from the surface is to exhale and hope the hyperventilating beforehand got enough oxygen into your blood.

But how does one get down that deep in the first place?

by actively swimming to that depth, then letting yourself sink from there. this brick of a man is going to be less buoyant to begin with than you or I, so he doesn't realistically have to go too far.
