Knee extensions for chronic obstructive pulmonary disease (COPD)

Before starting any exercise program, talk to your health professional. They may ask that you do specific exercises and will help you decide how often and how long to do them.

Start the exercise slowly and gradually. Either keep track of how long you can do it or count the number of times you can do it before you are mildly out of breath. Then rest and move on to the next exercise. Each week, increase the amount of time you do them or how many you do.

• Sit in a chair with your feet slightly apart.
• Breathe out as you straighten your knee and raise your leg.
• Breathe in as you bend your knee and return your foot to the floor.
