Lecture Notes

So we know by now that physical activity is important, but how much should we do? How much is enough? Do you ever hear people ask that question, "Well, okay, I know I should be physical active, but what should I do? How much should I do?" Our government recommends that adults get at least 150 minutes of moderate-intensity aerobic activity; so that could be similar to brisk walking; or 75 minutes of vigorous-intensity aerobic activity every week, and that equates to about 30 minutes every day of moderate exercise or physical activity. They also recommend that we get two or more days a week, all the major muscle groups in strengthening activities, and we'll talk about these recommendations a little further in the semester, but I wanted to present them here.
