The National Institutes of Health says we should all get at least 30 minutes of moderate physical activity most days to lower our risk for heart disease. Keeping active helps prevent arteries from getting clogged with fat and cholesterol which can lead to a heart attack. But you don’t need to be a gym bunny to squeeze a little cardio into your day. Unsure where to start? How about at home? Rearrange your furniture, give your living room a new coat of paint or hang some new art on the walls -- your heart will thank you! Do the heavy lifting next time you (or a friend) move and drop a cool 330 calories an hour.
