Your body is not only burning calories from your workout itself, but also from the energy used in regulating your temperature to keep you warm. Double the burn. It’s a win/win. - Strengthening your heart.

People tend to be more vigilant about warm-up exercises and stretching in cold weather more so than at other times of the year. Mentally you want to “warm up” when you go outside, no matter what your activity, so your body automatically craves a bit of motion in order to get blood flowing and help adjust to the temperature drop from being indoors. Warming up is a crucial part of any workout or sport, so if it becomes part of your routine during the winter, it will likely stick with you as the seasons change. Warming up keeps muscles limber and flexible and can help reduce the risk of tendonitis and sprains and strains.
