Designing an Exercise Program
To improve your heart and lung fitness, aim for 30 to 60 minutes of aerobic exercise three to four times a week.

Exercise for the Seriously Unfit
You can't walk across a room without huffing and puffing. Your arms get tired unpacking a bag of groceries. You're carrying more and more excess body weight. And you can't remember the last time you got any real exercise.

You know it's important to stay active but still find yourself falling back on old habits. What can you do? Planning for exercise isn't hard if you make it a priority.

Exercise: Before Starting an Exercise Program
