Winter Workouts: Or How I Accidentally Burned Calories Just Existing

Shoveling Snow: Roughly 370–715 calories per hour depending on effort and body weight, with vigorous hand shoveling on the higher end. 

Using a Snow Blower: Burns fewer calories — around 200 calories per hour while walking and pushing the machine.

Cold/Shivering: Cold exposure itself can increase energy expenditure through shivering and brown fat activation — estimates of 100–400 calories per hour are typical for shivering, although this varies widely with temperature and individual factors.
