Joy to the world! Co-founders Julie Rice (left) and Elizabeth Cutler share their secrets on staying trim and fit during the holidays.

The key to staying in shape…
Julie: Get out of your typical routine and get outside — go for a hike, ice skate, play in the snow with your kids…
And if you’re away on travel…
Julie: You can do a calisthenics routine in your room — push-ups followed by burpees and lunges. Use your body weight for resistance.
My motivation mantra…
Elizabeth: Sweat a little bit every day. It’s good for your mind and body. Find something you look forward to doing — exercise should not be something you check off your list, but something you want to do because it is joyful.
Best song to keep you energized…
Julie: The remix of Rihanna’s Diamonds with Kanye West.
The exercise that gives you the most bang for your buck…
Elizabeth: A SoulCycle class is ideal. In 45 minutes, you can burn anywhere from 400 to 700 calories, take a mental break (no cell phones allowed) and have fun exercising.
When it comes to diet, always…
Elizabeth: Eat in moderation. If there is something you love, you don’t have to totally avoid it. I will have one cookie versus ten.
Foods to focus on…
Julie: Fill up on vegetables and lean proteins.
The morning after a big holiday meal, remember to…
Elizabeth: Get on that bike and work it out!
And if all else fails…
Julie: Try again. You can make up for an indulgent meal by eating lighter at the next meal.
