A walk to the store. A stroll in the park. These routine trips may help women in their 40s, 50s, and 60s stay lean. Those who walked an average of 10,000 steps a day were more likely to be at a healthy weight than women who only hoofed it for fewer than 6,000 steps daily. To find out how much you’re walking, buy an inexpensive pedometer, or borrow one, and track your average daily steps over a week or so. - Medicine & Science in Sports & Exercise
