Set realistic goals

For most healthy adults, the Department of Health and Human Services recommends these exercise guidelines:

• Aerobic activity. Get at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. The guidelines suggest that you spread out this exercise during the course of a week. Greater amounts of exercise will provide even greater health benefits. But even small amounts of physical activity are helpful. Being active for short periods of time throughout the day can add up to provide health benefits.
• Strength training. Do strength training exercises for all major muscle groups at least two times a week. Aim to do a single set of each exercise, using a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions.

As a general goal, aim for at least 30 minutes of physical activity a day. If you can't set aside that much time, try several short sessions of activity throughout the day. Any amount of activity is better than none at all. Even small amounts of physical activity are helpful, and accumulated activity throughout the day adds up to provide health benefit.

Remember it's OK to start slowly — especially if you haven't been exercising regularly. You might start with five minutes a day the first week, and then increase your time by five minutes each week until you reach at least 30 minutes.

For even more health benefits, aim for at least 60 minutes of physical activity most days of the week.
