With David Blaine's advice. I didn't push it particularly far. Apparently most people can do 3:30 (Houdini's record) with these instructions taken from 4HWW:
DON'T TRY THIS UNDERWATER BECAUSE YOU CAN EASILY BLACKOUT AND DIE.
Equipment:
Stopwatch (http://www.online-stopwatch.com/full-screen-stopwatch/)
Definitions:
Tips for before you start:
Keep your eyes closed while holding your breath. Only open them to check the time every 30 seconds or so. This helps you stay relaxed. If you need something to think about, try going through the alphabet from A-Z and thinking of a friend's name starting with each letter. Don't panic about it, use celebrities or words if you don't have friends (Q is hard). It is normal to feel tingling, crazy vision, and start having abdominal spasms near the end if you push it. Eventually you either give up or black out, so watch out for sharp things.
The Steps:
Sit perfectly still in a position where you can relax your body
1:30 deep breathing
1:15 purging (if you feel like you’re going to pass out, do it less intensely)
Hold breath for target 1:30, no more
After 1:30:
Take 3 semi-purge breaths
1:30 deep breathing
1:30 purging
Hold breath for target 2:30 (you could probably do 3:30 on this step. Go for it if you want)
After 2:30
Take 3 semi-purge breaths
2:00 deep breathing
1:45 purging
Hold breath for as long as possible
After exhalation:
Take 3-10 hard semi-purge breaths until your recover
??
Profit
Post results or we will assume you died.
Addendum: I am not a doctor, but you probably shouldn't do this if you have heart problems, or seizures, or other weird problems.

Deep breathing: “Deep breathing” involves taking a big breath in through the mouth, holding for one second, and then exhaling for 10 seconds through your mouth through your almost-closed mouth with tongue pressed against your lower teeth. It should be a hissing exhalation and make a “tsssssss…” sound. All breathing and exercises are performed though the mouth.
Purging: “Purging” involves a strong exhalation as if you were trying to blow a toy sailboat across a pool, followed by a big but faster inhalation. David’s cheeks were puffed out as he demonstrated the exhalation (imagine the big bad wolf blowing the pigs’ homes down). Be careful not to heave or rock back and forth, which wastes oxygen. Keep as still as possible.
Semi-purging: Breathing between the above two. More forceful than deep breathing but less forceful than full purging. Used for recovering after each time trial.
