Firstly, patients with bronchiectasis are not suitable for intense physical exercise, especially during the onset of the disease. They should rest appropriately instead of engaging in excessive exercise, as overexertion can lead to a further worsening of the condition.

When the condition is stable, activities like walking, swimming, and brisk walking can be considered. However, the choice should be based on one's personal health status, and the exercise must be moderate. The intensity of the exercise should not be too high, nor should it be too exhausting, as excessive fatigue can also trigger the onset of the disease.
