You've heard it a thousand times over, and the message stays the same: Regular, heart-thumping exercise offers a multitude of health benefits, particularly for cardiovascular fitness. Perhaps clinicians (and health writers) keep bashing us over the head with that fact because of the eye-popping number of American adults who reported getting zero vigorous activity in a 2008 Centers of Disease Control and Prevention survey: 59 percent.
Bottom line: For a clean bill of health, the major health associations (including the AHA and the American College of Sports Medicine) suggest a minimum of 150 minutes of moderate-intensity physical activity each week—say, brisk walking that boosts your heart rate. This translates into 30 minutes of exercise on five days of the week. Twice-weekly strength training of eight to 10 exercises, up to 12 reps each, is also on their to-do list.
Whiteson at NYU Langone Medical Center suggests that those who don't have heart disease should bump that recommendation up to 60 minutes a day, five days a week of vigorous activity, where you're breathing pretty heavily and sweating. But he offers a concession: "You can break it up" into, say, three 20-minute sessions per day, since "the effect of aerobic exercise is cumulative." He also thinks those without heart disease should do strength training thrice weekly. Individuals with heart disease should always discuss a new exercise regimen with a doctor first, he says.
