* Cases diagnosed with COPD by a chest diseases specialist at Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital will be included in the study.
* The cases meeting the inclusion criteria will be randomized and divided into two groups, called the standard rehabilitation group (PRGr) and the inspiratory muscle training group (IMTGr).
* Initial exercise sessions and all evaluations of all cases will be performed in the hospital. The 2nd and 3rd training repetitions will be held at their homes via online synchronized videoconferencing. The exercise video will be sent to the smart phones of the cases who have completed 3 training sessions. Participants will be called once a week by phone and exercise follow-up will be carried out.
* All subjects will continue to exercise 5 days a week for 2 months. The standard PR consists of breathing exercises, peripheral muscle strength and self walking training. In addition, IMT was applied to IMTGr.
