- All adults should avoid inactivity. Some physical activity is better than none, and adults who participate in any amount of physical activity gain some health benefits.
- For substantial health benefits, adults should do at least 150 minutes (2 hours and 30 minutes) a week of moderate-intensity, or 75 minutes (1 hour and 15 minutes) a week of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity aerobic activity. Aerobic activity should be performed in episodes of at least 10 minutes, and preferably, it should be spread throughout the week.
- For additional and more extensive health benefits, adults should increase their aerobic physical activity to 300 minutes (5 hours) a week of moderate-intensity, or 150 minutes a week of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity activity. Additional health benefits are gained by engaging in physical activity beyond this amount.
- Adults should also do muscle-strengthening activities that are moderate or high intensity and involve all major muscle groups on 2 or more days a week, as these activities provide additional health benefits.

Moderate Intensity: Walking briskly (3 miles per hour or faster, but not race-walking), Water aerobics, Bicycling slower than 10 miles per hour, Tennis (doubles), Ballroom dancing, General gardening. To be at the minimum threshold, you would have to do these activities for 30 mins five times a week or 50 minutes 3 times a week.
Vigorous Intensity: Racewalking, jogging, or running, Swimming laps, Tennis (singles), Aerobic dancing, Bicycling 10 miles per hour or faster, Jumping rope, Heavy gardening (continuous digging or hoeing, with heart rate increases), Hiking uphill or with a heavy backpack. You can do these for 25 minutes, 3 times a week.
For additional benefits and most likely visible benefits you can add resistance training and the additional aerobic activity sessions explained above.
