There's nothing fun about having asthma. Your chest gets tight, you can't catch a good breath, you have coughing attacks and you have to pump yourself silly with steroid inhalers and pills just so you can breathe.
But if you have asthma that's triggered by allergies, you may find that getting your heart rate up helps - all that huffing and puffing gets the mucus out of your lungs. Going for a run or bike ride outside does wonders because you're breathing in all that fresh air.
But now that it's winter, inhaling that freezing cold air is sure to throw you into an attack.
You may need to change up your routine and join a gym. Use the treadmill, elliptical or other cardio machines. Or check out a spinning class.
If the stagnant air at the stinky gym doesn't work for you, winter's a great opportunity to try hot yoga. The deep breathing and stretching will do wonders for your lungs. Plus you'll get to stretch out all those tight muscles you built up.
