Walking, swimming, cycling, jogging, skiing, aerobic dancing or any of dozens of other activities can help your heart. They all cause you to feel warm, perspire and breathe heavily without being out of breath and without feeling any burning sensation in your muscles. Whether it is a structured exercise program or just part of your daily routine, all exercise adds up to a healthier heart. Take the first step by walking. It’s free, easy to do and when you have a walking companion, you’re more likely to stay motivated.
