I'll admit I'm a little lazy right now with breath holds (in regards to trying to stay under longer) because I'm mostly doing lane swimming in a pool where I don't want to scare the lifeguards and parties that are mostly shallow water. But I still try to keep it up, and have a habit of practising breath holds at random on land when relaxed. When doing my AIDA level 1 course though my static breath hold in the water went to 1:40 which I was pretty proud of considering how nervous I probably was, and hear that level 2 possibly requires a 2 minute breath hold to pass? Can't wait to do the level 2 course in June.
