The breathing exercise

You will likely have a really hard time focusing your mind on only the breathing exercise.

你好可能在刚开始练习呼吸运动的时间遇到很大困难。

Another experiment demonstrated that physical exercise, which was sufficiently vigorous to double the rate of breathing, had no effect on the frequency of yawning.

另一项实验表明，体育运动——尤其是剧烈的运动——可以使呼吸频率增加一倍，但这对打哈欠的频率没有影响。

Only at the time when one's breathing, mind and posture get into one, one is in the condition of yoga exercise.

只有当呼吸、意识和姿势结合成一体时，才是真正的瑜伽练习。
