Working out after the holidays is hard. I mean, it’s difficult enough to come back to your normal routine of setting an alarm, going to work, doing chores, and so on after spending a week lazing around with friends and family. But I personally have the hardest time getting back into fitness. I adapt quickly and efficiently to eating copious amounts of cookies and lying on the couch for hours on end. But by Jan. 2, my body and my brain are not exactly thrilled about a workout wake-up call.
