The present invention provides a nasal plug breathing exerciser with respiratory impedance, which includes a body with a partition line in the axial direction, one end of the partition line has a first end, and the other end of the partition line has a second end. The first end is for the user to wear in the nasal cavity, and the first end is formed with an opening, the second end is penetrated with an air inlet channel and an air outlet channel, and the air inlet channel and the air outlet channel are separated along a dividing line. The air inlet impedance valve body is arranged in the air inlet channel of the main body, and the air inlet impedance valve body resists the air flow during the inhalation action, so that the air flow is guided from the air inlet channel to the opening and enters the nasal cavity； the exhaust impedance valve body , It is set in the exhaust passage of the main body, and the exhaust resistance valve body resists the air flow during the exhalation action, so that the air flow is discharged from the opening to the exhaust passage, thereby providing the functions of inhalation resistance and exhalation resistance.本創作提供一種具呼吸阻抗的鼻塞式呼吸訓練器，其包含一本體，其軸向設有一分隔線，分隔線之一端具有一第一端部，分隔線之另一端具有一第二端部，第一端部以供使用者穿戴於鼻腔，且第一端部形成有一開口，第二端部穿設有一進氣通道及一排氣通道，進氣通道與排氣通道兩者沿分隔線隔開設置且個別連通開口；進氣阻抗閥體設於本體之進氣通道，進氣阻抗閥體於吸氣動作時阻抗氣流，使氣流自進氣通道導向開口並進入鼻腔；排氣阻抗閥體，其設於本體之排氣通道，排氣阻抗閥體於吐氣動作時阻抗氣流，使氣流自開口導向排氣通道排出，據以提供吸氣阻抗與吐氣阻抗的功能。
