Exercise & Fitness

Exercising regularly, every day if possible, is the single most important thing you can do for your health. In the short term, exercise helps to control appetite, boost mood, and improve sleep. In the long term, it reduces the risk of heart disease, stroke, diabetes, dementia, depression, and many cancers. The Centers for Disease Control and Prevention recommend the following:

For adults of all ages

  • At least 150 minutes of moderate aerobic exercise like brisk walking or 75 minutes of rigorous exercise like running (or an equivalent mix of both) every week.  It’s fine to break up exercise into smaller sessions as long as each one lasts at least 10 minutes.
  • Strength-training that works all major muscle groups—legs, hips, back, abdomen, chest, shoulders, and arms—at least two days a week.  Strength training may involve lifting weights, using resistance bands, or exercises like push-ups and sit-ups, in which your body weight furnishes the resistance.

For pregnant women

The guidelines for aerobic exercise are considered safe for most pregnant women. The CDC makes no recommendation for strength training. It’s a good idea to review your exercise plan with your doctor.

For children

At least 60 minutes of physical activity a day, most of which should be devoted to aerobic exercise. Children should do vigorous exercise and strength training, such as push-ups or gymnastics, on at least three days every week.

A Web-based way of tracking your physical activity level

If you want to keep tabs on your activity level and how many calories you're burning without buying a gadget, check out this government Web site: www.choosemyplate.gov It's run by United States Department of Agriculture (USDA). Why is the USDA in the exercise business? Because the department promulgates nutrition guidelines, and good nutrition necessarily involves energy balance, which means making sure that the amount of calories you're taking in should match the number you're burning — and be less if you are trying to lose weight. So although you can't eat physical activity, it's part of the USDA food pyramid. (Locked) More »
