i am extremley active and my pulse, if i assume correctly you mean pulseox, is usually 98-100 and my fev1 is usually 89-90% of expected if i remember correctly. i wrestle and weight lift to stay in optimum health and the results have been minimal flare ups and my body feels great! physical activity is excellant when it comes to improving you stats but be aware, physical activity can cause irritation and give you momentary shortness of breath which then wieghs on mental wellness and stuff although i am no docter..hopefully someday i will be... i would recommend physical activity.
