It’s easy to forget that walking is an aerobic activity. After all, more than 7 billion people do it every day. It’s low-impact, simple, natural, accessible, and has many health benefits. How can it possibly be an exercise, right?
The rule of thumb is to get at least 150 minutes of moderate-intensity aerobic exercise a week. Breaking the numbers down, that’s 30 minutes five days a week. This sounds like a small price to pay if you want to significantly improve both your physical and mental health.
Not even a third of American adults exercise on a regular basis, according to the Centers for Disease Control and Prevention. Just about 23% meet the federal guidelines for aerobic activity and strength training. But people in some places are less active than others — these are laziest cities in America.
