Dry air: I will make an assumption that the hot dry air where you are working out probably dried out the lining of your bronchial tubes causing it to bleed when coughing hard. That should heal up. If it does not heal up then see your dr. As coughing up blood can mean something more serious. Make sure you remain well hydrated.
