普通人练到3-4分钟非常容易。但是训练憋气自己要小心，因为经过训练后的憋气事实上身体是处在非常缺氧的状态下，而且你自己很明显的体会就是没有任何不适，好象根本就不想喘气。所以如果不注意或者心脏和肺功能不好的话，很容易就那么过去，也就是咱们常说的没气了。好的自由式潜水爱好者以及憋气高手也时刻面临这样的生命威胁，所以如果你按照方法练习憋气的话一定要当心，不要一味逼迫自己延长时间。
而正确的初步练习方法事实上我已经在“知道”里说过很多次了，先深呼吸，每一口都吸到不能再吸，再呼到不能再呼，整个过程要平静匀速。到大脑微有眩晕或困倦，再到这种感觉完全消失，大概中间要5分钟左右，这时候开始闭气，并看时间。你会发现即使是第一次练习，憋气1分半到两分也是很容易的，如果觉得不适比如憋不住了，或者脑袋又有些晕，就立即停止，不要勉强。每天练习几次就行，但中间间隔最好1小时以上，很快就会进步到3分左右。但是如果困倦感和眩晕感加强，就不要再练习，以免脑缺氧。而且不要强迫自己加长时间或加大训练量，我们毕竟不想创造什么奇迹，只是提高肺功能而已。
准备充分和准备不充分差别很大的。如果预先做1分钟深呼吸再下水，我可以憋4分钟。如果直接下水，大约2分40左右。如果让我先来个100米冲刺再下水，20秒我都憋不住。
已经憋了四年零三个月二十一天七小时二十六分八秒了，我还能坚持。
我一般是2分30秒到3分钟左右。硬撑到很难受最高3分10秒。那次差点晕过去。2分30秒是轻轻松松的。我还抽烟好多年了。所以我感觉正常人应该是3到4分钟吧。我也没训练过。
这些回复都很正确呀！我今年才十五岁，是女生，都能憋一分五十秒呢！不知道点踩的人身体有多差……这个慢慢练习，四五次后就能提升十秒到二十秒....只能说现代人身体差的太多了！！
