Hi guys, firstly wanted to say what a great forum! Lots of great information. I'm not new to freediving, but I do need some advice/tips. Basically my breath holds are crap. Static in a pool - 2 mins MAX. I've been getting some tips off this forum and others, and have tried doing 'breathe-ups'. i.e 3 minutes of: breathe in quickly, hold for 1 sec, breathe out over 10 sec and repeat. Is that right? Hopefully not because it's not helping! I'm hoping to do a free diving course soon, but that will be summer (jan/feb time). So any advice and help would be greatly appreciated. Also I do a lot of pool swimming and finish up with underwater swimming. Again I don't get beyond 30m, so not good, but was wondering, should I pushing through the urge to shoot to the surface. Does that feeling of pain/panic etc disappear?
