You won't find any calorie counting here.
When cold weather hits, it's tempting to hit the gym for every workout. But Reggie Chambers, a certified personal trainer at New York Personal Training, says it's best to bust it out in nature as much as you can. "Taking advantage of cold days to workout outside will help you torch more calories since your body has to work harder to keep you warm," he explains. Sure, there are a lot of variables to determine how many calories you'll actually burn (things like your age, sex, and weight all play a role), but doing the same exact workout outside versus inside could net you a better burn.
