The same technique of diving used by free divers but nowadays is not popular. They were blowing out air ay the start of the dive to have smaller volume. The bad thing with that technique was that there was a possibility of collapsing the pleura and lungs because of the low resist of the lung to the change of environmental pressure! This was happening at 20 - 30 m where the pressure is 3-4 atm, At the 400m of the depth the pressure is 41atm!!!!!

very interesting. BBC nature shows are always the best. America cant make good interesting shows like this anymore. Most of the stuff on History and Natgeo is garbage. They still have some good stuff but mostly they are stupid documentaries about 2012 and disaster. But that show life after humans is pretty good.
