I've been talking a lot about allergies because they seem to be hitting everyone especially bad right now and nothing can kill a good workout like a sneezing fit. Trust me, I proved this theory true on Saturday. Allergies do not need to keep you from working out all together, you just may need to tweak your plan to work around your allergies. Here are a few ideas:

• Avoid morning workouts. Allergens peak from 5-10 a.m. to noon, which means if you're a morning exerciser you may want to hold off until later in the day.
• If the rain rolls in, that doesn't mean you have to head to the gym. In fact, rain washes away some of the pollen [1], which means that one of the best times for an allergy sufferer to work out outdoors is right after it rains.
• Avoid exercising in places where the pollen is at its greatest (i.e. parks, fields, trails, etc.) and stick to places that have a lower pollen counts (i.e. beaches, gyms, basketball or tennis courts, etc.).

If all else fails, hit the gym. Don't let a little pollen stop you on your quest for health!
