Nick,

If you can do 10 to 15 minutes of light cardio without causing symptoms, it is probably OK. But, if you are doing it while you are symptomatic, you might want to back off to a sweat free level. The Buffalo Protocol has information about exercise levels.

FYI,
It is helpful if the Post Reply button at the bottom left is used rather than the Reply button in bottom right of the last post. The Post Reply button does not quote the entire post. When the entire post is quoted, it is easy to miss a post and question that someone wanted addressed. I missed the exercise question because it was buried with the long page of quoted posts. I can't imagine what it is like to try to scroll through long pages on a tablet or smart phone.

Many just have not noticed the Post Reply button.
