Hi guys I recently started doing cardio again after a 8 month layoff. I do p90x type cadio. Anyway after a few minutes my lungs started hurting as well as spitting up fluid. Is this a normal part of it? I know im not in cardio shape right now but I used to do these workouts no problem. Could this be athletic asthma or do I just have to push through it? I finished the workout but had to take alot of breaks.
