Recently quit smoking. Heard that vigorous cardio exercise could actually be damaging. True? -
I am training for a mens competitive ultimate frisbee team and we do a lot of sprinting, could this actually be damaging on my newly smoke free lungs?
Why do it? Anything in excess is bad for the body, and vigorous cardio exercise is not recommended especially when you have just quit smoking. Give your body a time to heal by practising moderation.
