Here are tips on how to start and stay active in winter. If you are not used to exercising, start by working out at home until you get into the habit of it. Working out with a friend or a committed group will help you stay motivated. If possible, do a quick 15-minute exercise before your work to kick start your day energetically. A lot of brands have designed workout gear and thermals that are suitable for winter to keep you extra warm while exercising.
