You really can shiver off the calories this winter, according to personal trainers and exercise physiologists.
The body's primary goal is to maintain stasis, or stability, and that includes keeping a steady temperature.
So, in the cold, the body needs to burn extra fat, to produce energy to heat it back up to the ideal temperature.
But there's a trick to it, and personal trainer Max Zeumer of the 13th street New York Health and Racquet Club told Daily Mail Online his surprisingly fun tips for how to optimize your cold weather workout.
Working out in the cold weather can help you shake off some extra calories
Why shivering makes you burn calories in the cold
During the winter, the body ramps up its production of a chemical called ATLPL, which helps it to store up fat for the evolutionary scarce season, so staying active in the winter is important to counteracting that.
What's more, with the right workout plan, you can take advantage of your shivers, says Zeumer.
When you work out in the cold, 'your body will work really hard to stay warm and burn a ton of calories to do it, but that really only starts when you're shivering,' he says.
The cold acts as a 'thermal stressor,' forcing the body's temperature regulation out of wack, says Jason Castano, a trainer and co-owner of Sports Loft NYC.
To keep the core, vital organs at the right temperature, blood flow to the extremities is reduced, and kept concentrated closer to the heart and internal organs.
The heart rate and metabolism slow, trying to save up energy and keep the warm blood in place.
That's when the shivering starts. Those shakes are a series of fast muscle contractions and releases, a way for the body to produce some extra warmth by burning energy stored in fat.
Once you get into a relatively consistent, high intensity workout - though you'll feel like you're working harder at first, against your slower heart rate and metabolism - the body begins warming up from more robust fat burning.
As your heart rate rises, blood and warmth return to your hands, feet and other extremities, and shivering is no longer necessary.
Once you hit that point, you're burning calories as you would during exercise at any temperature.
