When it's cold, it can be tempting to stay snuggled up indoors. Try to
get out and about though, especially to that Zumba class. People who
exercise regularly throughout the cold and flu season are 50% less
likely to end up coming down with a winter bug, a 2010 study found. They
tend to feel brighter too.
Don't forget: The new trend for interval training
means super quick, but still effective, workouts. Or - if the snow is falling - keep active indoors with a fitness DVD
. No excuses!
