Sorry not replied before. Copd will require a much more comprehensive programme than just a best single exercise. You really ought seek a good experienced respiratory physio locally. Perhaps I’ll do some more videos in the subject as you’ve prompted me. Thanks for the suggestion. Have you come across the active cycle of breathing technique. You’ll find it with a Google search. It is a series of varying size breaths followed by huffing to clear secretions. Deep breathing and I feel more importantly relaxation breaths after will work well.
