Sometimes it can be hard to tell the difference between allergies and the common cold. There are more than a hundred strains of cold viruses. Each tends to become widespread at certain times of the year, which is why you may mistake a cold for a seasonal allergy.
Q: How often should I work out? A: The amount of exercise you need depends on the type of lifestyle you want to maintain. For beginners, most experts recommend at least 20 minutes of exercise three times a week. These 20 minutes can be a combination of four 5-minute sessions of exercise, two 10-minute sessions or 20 continuous minutes. Just doing something is better than no exercise at all.
