The US Centers for Disease Control considers all of the activities below to be "vigorous," which means you're burning more than seven calories per minute just by doing whatever life throws at you, such as…
Pushing a disabled car
Moving or pushing heavy furniture (75 pounds or more)
Running up a flight of stairs while carrying a suitcase or load weighing 25 pounds or more
Standing, walking or walking down a flight of stairs while carrying objects weighing 50 pounds or more
Grocery shopping while carrying young children and pushing a full grocery cart, or pushing two full grocery carts at once
Pushing a non-motorized lawn mower
Gardening and yard work: heavy or rapid shoveling (more than 10 pounds per minute), digging ditches or carrying heavy loads.
So whenever you're racing to catch a plane or simply helping a neighbor who's out of gas, take comfort in the fact that you're burning calories in a big way.
