Driving past the gym to the mall for holiday shopping becomes easy unless you've committed to yourself and your trainer that you'll fit exercise into your life. Muscle is your "metabolic Spanx" that holds everything together, something you'll appreciate all too well when you put on that little black dress come New Year's Eve.
More importantly, exercise makes us all happier...the more we move, the happier we get. Fit people are simply happier people...better spouses, better parents, better people.
If the gym is not an option for you, try a home workout video -- (the ALL NEW P90X3 is a great choice!) or even try some of the OnDemand workouts. You can get your workout in about the time it takes to find a parking space at the mall.
