Exercising? Take it up a notch
Want to get the most out of your workouts? Try interval training! This simply means alternating bursts of intense activity with intervals of lighter activity. Take walking. If you're in good shape, try incorporating short bursts of jogging into your regular power walks. If you're less fit, alternate leisurely walking with periods of faster walking. (For example, if you typically walk outdoors, walk faster between certain mailboxes, trees or city blocks.) The more vigorously you exercise the more calories you'll burn, even if you increase intensity for just a few minutes at a time.
Focus on fit when shoe shopping
To find shoes that fit properly, try these tips: 1. Have your feet measured. Shoe size can change as you age. 2. Ask the salesperson to measure both feet. If one foot is larger than the other, try on a pair that fits your larger foot. 3. Shop for shoes later in the day after you've been walking for some time, when your feet are at their largest.

How much exercise do you need?
For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. Moderate aerobic exercise includes activities such as brisk walking or swimming. Vigorous aerobic exercise includes activities such as running or aerobic dancing. The guidelines suggest that you spread out this exercise during the course of a week. The guidelines also recommend that you do strength training exercises for all major muscle groups at least twice a week.
