Put It To The Test

So what should you do? Start exercising! We don’t know exactly which exercise is best. Almost all of the research has looked at walking, including the latest study.

“It’s likely that other forms of aerobic exercise that get your heart pumping might yield similar benefits,” says Dr. McGinnis.

How much exercise is required to improve memory? These study participants walked briskly for one hour, twice a week. That’s 120 minutes of moderate intensity exercise a week. Standard recommendations advise half an hour of moderate physical activity most days of the week, or 150 minutes a week. If that seems daunting, start with a few minutes a day, and increase the amount you exercise by five or 10 minutes every week until you reach your goal.

If you don’t want to walk, consider other moderate-intensity exercises, such as swimming, stair climbing, tennis, squash, or dancing. Don’t forget that household activities can count as well, such as intense floor mopping, raking leaves, or anything that gets your heart pumping so much that you break out in a light sweat.

Don’t have the discipline to do it on your own? Try any or all of these ideas:

Join a class or work out with a friend who’ll hold you accountable.

Track your progress, which encourages you to reach a goal.

If you’re able, hire a personal trainer. (Paying an expert is good motivation.)

Whatever exercise and motivators you choose, commit to establishing exercise as a habit, almost like taking a prescription medication. After all, they say that exercise is medicine, and that can go on the top of anyone’s list of reasons to work out.
