Pulmonary rehabilitation exercises are crucial for improving lung capacity and overall respiratory function. Some of the top exercises that can be done at home include deep breathing exercises, pursed lip breathing, diaphragmatic breathing, coughing exercises, arm exercises, leg exercises, walking or jogging in place, yoga, and stretching exercises. These exercises can help strengthen the muscles involved in breathing, improve oxygen flow, and increase lung capacity over time. It is important to consult with a healthcare provider before starting any new exercise routine, especially for individuals with respiratory conditions.
