Plan ahead
No time for your usual spin class, yoga session, or weight-training routine between the holiday hustle and bustle? Overcome your workout impediments with a little creativity. For example, plan active get-togethers with family and friends. Start a new tradition of a family walk to view decorated houses in your neighborhood. Or, while gift shopping at the mall, strap on a pedometer. Beth Shaw, founder of YogaFit Training Systems in Torrance, California, suggests aiming to take 10,000 steps every day during the holiday season.

Too late?
If a week (or two or three) slides by, it's not too late to get back on track. "View the next day as an opportunity to make a correction," says Shaw, and start by adding 30 minutes of walking to your day. If you're more likely to exercise with a partner, check out www.walkers.meetup.com to find a walking buddy in your area. "Schedule gym time—just like you would make a business or doctor's appointment. And then stick to it!" says Shaw.
