What would be the correct intensity for someone with a mild to moderate level of COPD to exercise?

For individuals with mild to moderate COPD, exercise intensity should generally be moderate, often defined as 60-70% of maximum heart rate or a perceived exertion level of 4-6 on a scale of 0-10. It's important to focus on activities that promote endurance, such as walking or cycling, while ensuring that the person can still talk comfortably during exercise. Regular monitoring of symptoms and oxygen saturation levels is crucial to avoid overexertion. Consulting with a healthcare provider or a pulmonary rehabilitation specialist is recommended to tailor an appropriate exercise program.
