Energy for the rest of us

More Energy for the Least Effort

Ten-minute workouts, easy walks and small daily habits, built on what the federal guidelines actually say.

You do not need a gym or an hour a day to feel less tired. The federal guidelines count every bout of activity, however short, and the first minutes bring the biggest gain. A local gym or fitness class can coach you; these guides show what to fit into an ordinary day.

Each one draws on HHS, the CDC, the National Institutes of Health and other public sources. Local resources on parks, walking trails and community fitness can help with the rest.

Five Facts That Charge Everything Else

Plug these in first: the rest of the site is built on them.

20%
Any bout counts
Under the Physical Activity Guidelines for Americans, bouts of moderate-to-vigorous activity of any length count toward the weekly total. Three ten-minute sessions add up like one of thirty. More in The 10-Minute Home Workout: No Equipment, No Excuses.
40%
150 minutes is the target, not the start
Adults should aim for 150 to 300 minutes a week of moderate activity or 75 to 150 of vigorous, but the guidelines find no threshold that must be passed before benefits begin. More in How Much Exercise Do Adults Need? The Federal Numbers, Explained.
60%
Two days of strength
Muscle-strengthening that works all major muscle groups on 2 or more days a week. The National Institute on Aging says one set of 8 to 12 repetitions of each exercise is effective. More in Strength Training With No Gym: Two Days a Week at Home.
80%
Sleep is the charger
The CDC recommends 7 or more hours of sleep a night for adults aged 18 to 60, and the NHLBI says a nap should last no more than 20 minutes. More in Sleep and Energy: The Habit Everything Else Depends On.
100%
Caffeine has a cut-off
The FDA cites 400 milligrams a day, about two to three 12-ounce cups of coffee, for most adults, and the NHLBI says the effects can last up to 8 hours. More in Caffeine and Energy: How Much, When, and When to Skip It.

Quick answers

Switch On an Answer

Short answers, each with the guide that goes further.

Do ten-minute walks really count?

Yes. The Physical Activity Guidelines count bouts of any length toward the weekly total, so three ten-minute brisk walks a day on five days make 150 minutes. See Walking Plans for Busy People: Three Weeks That Fit Real Schedules.

How do I know I am working hard enough?

Use the talk test from the guidelines: during moderate activity you can talk but not sing; during vigorous activity you cannot say more than a few words without pausing for a breath. See The 10-Minute Home Workout: No Equipment, No Excuses.

Do I need a gym for strength training?

No. Body-weight moves and household items work. The National Institute on Aging says one set of 8 to 12 repetitions is effective and advises not working the same muscle group two days in a row. See Strength Training With No Gym: Two Days a Week at Home.

I sit all day at work. What helps?

OSHA says sitting still in one posture for long periods is not healthy, however good the posture. It suggests changing position often, doing some tasks standing, such as phone calls, reading and meetings, and getting up to walk for a few minutes now and then. See Standing and Moving During the Workday.

How much water do I need?

The National Academies set adequate total water intake at about 3.7 liters a day for men and 2.7 liters for women, from all drinks and foods, and found most healthy people meet their needs by drinking when thirsty. See Hydration and Focus: How Much Water You Actually Need.

How much caffeine is too much?

For most adults the FDA cites 400 milligrams a day, about two to three 12-ounce cups of coffee, as an amount not generally associated with negative effects. See Caffeine and Energy: How Much, When, and When to Skip It.

Is a nap a good idea?

A short one can be. The NHLBI says adults should nap for no more than 20 minutes. See Sleep and Energy: The Habit Everything Else Depends On.

Does morning light make a difference?

Light and dark have the biggest influence on the body clock, according to NIGMS, and the NHLBI advises avoiding bright screens in the hour before bed. See Morning Light and Energy: Working With Your Body Clock.
