1. Work Out 5 Days a Week

It's not your imagination: Our bodies simply become higher maintenance after 40. Indulgences of food or drink are quicker to take revenge. Muscles require more maintenance. Screening tests become more important. So there's a lot to remember -- and yet the wellness precautions keep coming, with new dos and don'ts every passing year. Can anyone do it all?

Actually, no. And if you try, say experts, you may end up throwing in the towel on some of the essentials, as well as what's helpful but optional. So find out where you can settle for good enough and still enjoy great health.

Rule 1: Work out 30 to 60 minutes a day, five days a week.
The Midlife Shortcut: Catch up when you miss workouts.

To reduce the risk of heart disease, cancer, and osteoporosis -- all big concerns for women over 40 -- experts urge us to exercise at least 30 minutes a day, five days a week (and for maximum health benefits, make that an hour rather than half an hour). But daily workouts can be difficult to fit into a life crammed with work and family responsibilities. Then there's the knee and joint pain that many women experience after years of pounding their way through "healthful" exercise.

Why there's wiggle room: The cumulative hours -- the total time you clock each week -- is what really counts. In fact, the weekend warrior has gotten a bad rap, says exercise physiologist Jane Roy, PhD, of the University of Alabama at Birmingham. If you're too busy Monday through Friday, weekends are a great time for getting in two or more hours of enjoyable exercise a day. You can catch up by spending a weekend morning or afternoon playing tennis with girlfriends, taking back-to-back aerobic and Pilates classes, or going for a long walk or run.

Then, during the week, concentrate on interspersing sedentary activities such as computer work with small but frequent movement breaks, Roy adds.
