Good stuff, thank you.
I’m guessing those aren’t good exercises to do while driving, either. 
Outstanding Thanks !
Not the most ideal time to do breath hold tables…
And about the dangers of doing the wet breath hold alone… I did read an article in a Navy magazine about a Navy SEAL that was doing some breath hold practice on his own at the local pool in Hawaii. He was told by the lifeguards that he wasn’t allowed to do underwater breath holding, but he told them that he was a SEAL, and the shouldn’t worry at all. Navy SEAL takes a deep breath and lets himself hit the bottom of the pool (4 foot shallow end) Over the next 20 minutes or so, as the lifeguards are under their shade umbrellas, various people comment on the man laying on the bottom of the pool… “Oh, it’s just a Navy SEAL doing some practice” they say, shrug their shoulders and move on. It takes them about 30minutes to realize the Navy SEAL had drowned.:eek:
Dude, where I can I find more videos like this. These are sick.
I have yet to find a video that comes close to being as cool as the base jumping one, but you can find some high speed low drag videos by looking for " William Trubridge" “Freediving record” etc etc.
