자유형 호흡법 음파 음파헙 이거 정답 맞아요? 결국은 이호흡으로 넘어가야 해요

So, when I teach in the field, I tailor my instruction to each member. For those who can breathe out clearly and relax without making a sound, I let them maintain that good habit. However, for those who struggle with this and are afraid of the water, I start by helping them get used to it by having them make an 'mmm' sound. After all, there is no absolute right answer in swimming.
