title says all, how long can you? Doesn't matter whether underwater or not.
When I used to swim I could hold it for around 2:30 min underwater, then I stopped and I started smoking.... Last year I could hold it for only 30-45 seconds, and now that I started doing cycling, I just found out I can hold it for 1:30-1:40 no problem, and I still smoke 8-10 cigs a day.and you guys?
having a naturally low heartrate helps too. i have a low heartrate, and an unnaturally high VO2 max (my body uses a higher percentage of the oxygen it intakes than most peoples bodies), so i'm sure i can do better than 1 minute

there'd probably be NOTHING more terrifying than facing an army riding moose. They're fucking huge, aggressive, unpredictable and fast. Mount up.- gordie.$
Sit for a few minutes after, cause walking after a three minute hold is hard. Don't exhale really quick, because the rapid decompression of your lungs will make your blood rush there for some reason (Don't know why, but that's what some guy told me), until you have little in your brain, and that's called a shallow water blackout. I highly recommend reading about safety and shit before you go trying for really long holds, because doing it incorrectly and forcing yourself is how you get brain damage and nasty shit like that.
