Moderate Excercise: How Intense Must It Be?

How do we define “moderate exercise”? The question is prompted by federal guidelines recommending that we get 150 minutes of moderate — or 75 minutes of vigorous — aerobic exercise each week. American guidelines suggest that during moderate exercise, you should be able to “talk, but not sing.”  It seems subjective, so researchers at York University in Toronto set out to determine how realistic people’s perceptions are about how intensely they exercise. They found that volunteers overestimated how hard they were exercising and so might not obtain the full benefits they were expecting. Read the full article for information about how the study measured exercise intensity. The article concludes with a bit of encouragement: “any amount of physical activity at almost any intensity will have some health benefits.”
