Well, that’s a good question. Is it better to exercise inside or outside? The EPA has actually stated that indoor air is more polluted than outdoor air, and that has to do with the amount of cleaning products that have toxic chemicals in them, wood flooring that off-gases toxic chemicals, carpet and furniture that off-gases toxic chemicals. So we actually know that indoor air is more polluted than outdoor air. So in terms of, "Do you exercise indoors or outdoors?" well, one, it depends on where you live because certain cities have very high air pollution, and then it also depends on, are you exercising in your own home where you’re controlling the amount of chemicals that are being used, and, how clean your air is, versus exercising at a gym where perhaps you don’t have as much control over the indoor air quality? So it’s really a question about indoor air quality versus outdoor air quality, and that has to do with where you live, and where indoors you’re exercising.
