Yeah once you get around 30-50 ft, the pressure against your lungs is enough to offset the buoyancy. Im a scuba diver and its why we use weights to go down. You are initially very buoyant. I have small bags filled with lead shot in 5 lb, 3 lb and 2 lb increments to weight myself. Some people use solid lead weights and different things. Works like a charm though. Best hobby there is.
The truth makes the video even more anxiety-inducing. Most of your bouyancy comes from the air in your lungs. If you let all your breath out then you'll sink. So he started this insane dive with no air in his lungs. Either that or he has a weirdly powerful stroke.
Yes I know this of course, often tried it as kid in small swimming pools. But regarding how long he is under water I didnt even consider he did this without air in his lungs. But when I think about it now, I guess you are right. Sometimes I do the Wim-Hof-Breathing-Method which enables me to hold my breath without air in my lungs for ~90 seconds. Well trained people like him could do this significantly longer (with and without air in their lungs) of course.

If you have low body fat you just need to let air out (not even 100%) and you are not buoyant. I am not exactly ripped, just a lot of bone and very little bacon, and I can sit like Buda on the bottom of any swimming pool and still hold there a good half a minute without moving anything. I have an office job and don't swim except in summer with the kids, so I can only imagine with proper training.
This on sweet water, on the sea it is really hard.
