A Short-Walk Plan That Builds From a Standing Start to 150 Minutes a Week

Your shoes are by the door, and there’s still half an hour of light left after dinner. If you’ve been meaning to start walking for exercise, that half hour is enough to begin.

The Department of Health and Human Services (HHS) asks adults for at least 150 minutes of moderate activity a week in its Physical Activity Guidelines for Americans, plus muscle strengthening on 2 or more days. The second edition, from 2018, also dropped an old rule that only bouts of 10 minutes or longer counted, so a walk of any length now goes into your weekly total. Starting from zero, the plan below gets you to 150 minutes in as little as four weeks, or eight at a gentler pace.

1. Pick one fixed time slot

Choose a time you can repeat six days a week, and tie it to something that already happens every day, like the morning coffee, the school drop-off or the end of dinner. A walk that follows a fixed cue needs less willpower each time.

Habit research supports the cue. In a study published in the European Journal of Social Psychology in 2010, volunteers picked one daily health habit, such as a 15-minute run before dinner, and repeated it in the same setting. Reaching peak automaticity took a median of 66 days, with a range from 18 days to a predicted 254.

That means the four-week ramp won’t finish the habit for you. It gets the minutes in place while the habit catches up, and the slot written on six days of your calendar is your first piece of proof.

2. Start with 10 minutes

Your first walks should feel almost too easy. Ten minutes at a comfortable pace is the whole job for week 1, and six of them make 60 minutes for the week.

That 60 is a real milestone. The HHS guidelines plot health benefit against weekly minutes, and the biggest gain on that curve comes from going from no activity to just 60 minutes a week.

If 10 minutes in one go is too much, split it. The 2008 edition counted only bouts of 10 minutes or more, for lack of evidence on shorter ones. By 2018 the advisory committee had concluded that bouts of any length add to the benefit, and the guidelines now say even climbing a few flights of stairs counts. Two 5-minute walks go in your log the same way one 10-minute walk does.

Without that floor, a beginner’s shortest walks count from the first day.

HHS says adults with no diagnosed chronic condition and no symptoms such as chest pain or pressure, dizziness or joint pain most likely don’t need a provider’s sign-off for a plan this gradual. If you live with heart disease, diabetes or arthritis, or have one of those symptoms, talk to your clinician before you start.

3. Use the talk test for pace

Week 1 can be a stroll. From week 2 on, you want most of each walk at moderate intensity, and one common gauge needs no gadget.

“As a rule of thumb, a person doing moderate-intensity aerobic activity can talk, but not sing, during the activity.”

Physical Activity Guidelines for Americans, 2nd edition

If you could sing a chorus, speed up. If you can only get out a few words before you pause for breath, you’ve reached vigorous effort. Each vigorous minute counts about double toward the weekly goal, but it’s more than a beginner needs. HHS also offers a 0 to 10 scale where sitting is 0 and your hardest effort is 10, and moderate sits at a 5 or 6.

The talk test adjusts to your own fitness, which a speed number can’t. HHS notes that older or less fit adults may find a brisk walk feels vigorous, and that they still gain from starting at a lighter effort and building up. A phone call makes a handy check, since you’ll hear yourself run short of breath.

4. Add 5 minutes per walk each week

Once week 1 feels routine, lengthen each walk by about 5 minutes a week and keep the number of walks the same. That puts you at 15-minute walks in week 2, 20 in week 3 and 25 in week 4, for weekly totals of 60, 90, 120 and then 150 minutes.

Example: six walking days and one rest day, with strength work on Thursdays from the start and on Mondays from week 3.

Watch the size of each jump in percentage terms. HHS ties injury risk to the gap between what you usually do and what you ask of your body. Its example is a 20-minute weekly increase, a 10% step for someone who already does 200 minutes but a 50% step for someone who does 40. Going from 60 to 90 minutes is a 50% jump of exactly that kind, even though it’s only 5 extra minutes a walk.

So treat the calendar as a suggestion. The guidelines say older adults appear to need 2 to 4 weeks to adapt to a new level of activity. If you’re past 60, or a week leaves your feet or knees sore, repeat it before you move on. Holding every level for two weeks turns this into an eight-week ramp that still ends at 150 minutes.

You’ll know the step is complete the first week your log adds up to 150 minutes.

5. Add two days of strength work

Walking covers the aerobic half of the guidelines. The other half asks for muscle-strengthening activity on 2 or more days a week that works the legs, hips, back, abdomen, chest, shoulders and arms. Bands and body weight count, and HHS says one set of 8 to 12 repetitions of each exercise works when you go until another would be hard.

Strength is the half most adults skip, and national survey data shows it. In the CDC’s National Health Interview Survey for 2020, 24.2% of adults met both guidelines, while another 22.7% met the aerobic one alone. Just 6.8% did strength alone, and 46.3% met neither.

HHS suggests easing in here too, with strength work 1 day a week at a light or moderate effort before you add a second. A starter set can be sit-to-stands from a sturdy chair, push-ups against a wall or a kitchen counter, and seated rows with a resistance band looped around your feet.

When you can do 12 clean repetitions of a move, make it harder with a slower count, a firmer band or a lower surface for the push-ups.

6. Count minutes, not steps

The guidelines are written in minutes at a given effort, so minutes are the number to keep. A step count can’t tell a brisk 20-minute walk from a slow lap of the grocery store.

A paper calendar on the fridge works as well as any app.

Write each walk’s minutes on its day and add up the week on Sunday, your rest day. Short bouts go on the same line, so a brisk 6-minute walk from a far parking spot counts if you passed the talk test while you did it.

If you miss a day, skip the urge to make it up with one long walk. Add 5 minutes to two of the next walks instead, or repeat the week. That 2010 habit study found that a single missed day did little harm to the habit, though a run of missed days left it less automatic.

Week one, in five lines

• Write your walking slot on six days of this week’s calendar.
• Set your shoes by the door the night before each walk.
• Walk 10 minutes on each of those days, in one go or two, at an easy pace.
• On Thursday, add one set each of sit-to-stands and wall push-ups after the walk.
• Write down every walk’s minutes and look for 60 on Sunday.

Stop the plan and call a clinician if a walk brings on chest pain or pressure, or if dizziness or joint pain appears for the first time, hits hard or won’t go away.
