Don't wait to feel motivated
In 10 studies of 3,899 people, 46% of those who intended to be active didn't follow through. A plan and a routine carry you on the days motivation doesn't.

How to stay motivated to work out: build the habit, enjoy it, and restart when you stop
Motivation comes and goes for everyone. In studies, nearly half the people who meant to be active didn't follow through, so the trick isn't to feel more motivated: it's to build a routine that keeps going on the days you don't. Exercise becomes a habit in weeks to months, not 21 days, and missing a session doesn't undo it.
This guide covers why intentions fail, how long a habit takes, planning when and where, goals and tracking, choosing something you enjoy at an effort that feels good, working out with others, rewards, a 10-minute plan for low days, what to do after a missed week, and when low motivation is something else, such as low mood.
The short version
A habit takes weeks to months
Everyday habits took anywhere from 18 to 254 days to become automatic in one study. Across studies, the middle figures were 59 to 66 days, and going to the gym took about 2 to 3 months.
Plan when and where, and track it
Planning raised physical activity across 41 trials, goal setting had a medium effect, and keeping a record worked best alongside a goal or feedback.
Pick something you enjoy, at an effort that feels good
How good exercise felt during the session predicted whether people kept going. When new exercisers chose an intensity they found pleasant, they came to the gym 77% more often over 8 weeks.
Expect to miss sessions, and restart fast
Missing a day didn't undo a habit, and in 61,293 gym members the best of 54 programmes rewarded coming back after a missed workout. Most people who drop out do so in the first 2 to 3 months.
Small counts
Short bouts were kept up as well as long sessions, and the UK guidelines say there's no minimum: some is good, more is better. If low mood is the barrier, our depression guide can help.
Motivation, intention and habit
Three different things
Motivation is wanting to do something; it rises and falls with mood, sleep, stress and the weather. An intention is a plan to do it. A habit is doing it more or less automatically when a cue comes up: a time, a place, the end of the working day.
Why intentions fail
In 10 studies, 42% of people intended to be active and were, but 36% intended to and didn't: nearly half of those who meant to. The gap is normal, which is why plans, cues and habits matter more than willpower.
Source 1
Kinds of motivation
Doing it because you feel you should, because you value what it gives you, or because you enjoy it. Valuing the result helped people start; enjoyment, challenge and company went with keeping going. Exercising mainly to change how your body looks gave mixed results.
Source 15
Why people stop
Lack of time is the most common reason, and most people stop in the first 2 to 3 months, while building up. Sessions that feel unpleasant predict stopping too.
What the evidence says
Intentions often failStrong evidence
Across 10 studies of 3,899 people, 46% of those who intended to be active didn't follow through.
Source 1
Habits take weeks to monthsEmerging evidence
In 96 volunteers who repeated a daily action, it took 18 to 254 days for it to become automatic, and missing one day didn't set it back. A review of 20 studies found middle (median) times of 59 to 66 days, with individuals anywhere from 4 to 335 days; most of the studies were at high risk of bias. In gym attendance records, gym-going took about 2 to 3 months to become a habit, as the authors' correction gives it.
Consistency builds the habitEmerging evidence
In 111 new gym members over 12 weeks, at least 4 sessions a week for 6 weeks was the minimum to establish a habit, and consistency, simple routines, the setting and enjoyment predicted it. This was one observational study.
Source 6
Planning helpsStrong evidence
Planning raised physical activity across 41 trials with 5,439 people (a standardised effect of 0.35), more when it was face to face and followed up.
Source 7
If-then plans need backing upMixed evidence
In 13 trials, if-then plans ("if it rains, I'll do the home session") didn't raise activity significantly overall, but did when they were reinforced, and the trials with no effect lacked plans for obstacles.
Source 8
Goals and tracking work best togetherStrong evidence
Goal-setting programmes had a medium effect on activity across 45 studies of 5,912 people. Keeping a record was the most effective single technique across 122 evaluations, especially with goals or feedback. Activity trackers added about 1,800 steps a day across 39 reviews.
How it feels predicts whether you keep goingEmerging evidence
Across 24 studies, feeling good during moderate exercise predicted future activity; how people felt afterwards didn't. In a trial of 47 new exercisers, choosing an intensity for pleasure gave 77% more gym sessions over 8 weeks. Self-chosen effort felt better than a set effort when the set effort was hard.
Doing it for yourself lasts longerEmerging evidence
In 66 mostly cross-sectional studies, enjoyment and challenge went with sticking at exercise long term. Programmes that support people's own choices raised their motivation and healthy habits modestly across 73 studies.
Planning, reminders and comeback rewards raised gym visitsStrong evidence
In 61,293 gym members, 45% of 54 four-week programmes raised weekly visits by 9 to 27%. The best rewarded coming back after a missed workout. Only 8% had effects that lasted after the programme ended.
Source 19
Most dropouts come earlyEmerging evidence
In 947 adults in three exercise trials, 31% dropped out, two-thirds of them before or while building up to the full programme, and lack of time was the most common reason. In GP exercise referral schemes, about 43 to 49% kept going; older people were more likely to start and stick with it.
Support from others goes with being activeEmerging evidence
In 54 studies of older adults, social support went with more activity. Most studies were snapshots, so this shows a link, not cause and effect.
Source 17
Make it a habit
Plan the session, not the feeling
Put the session in your week like an appointment. Behavioural activation, a talking therapy for depression, works the same way: schedule the activity rather than waiting for motivation to come first, as our depression guide explains.
Source 1
Same time, same place, same first move
Tie it to something you already do, such as straight after work, keep the session simple, and do it at least 3 or 4 times a week while the habit forms if you can (any activity counts). Give it 2 to 3 months.
Make the start easy
Kit out the night before, bag by the door, the route or the first exercise decided. The smaller the first step, the more likely you are to take it (our suggestion).
Plans, goals and tracking
Write down when and where
Which days, what time and where. The NHS's own tip is to think about where and on which days you're going to exercise, and when in the day you can fit it in.
Plan for obstacles
Add an if-then plan for the likely problems: "If I work late, I'll do the 20-minute session at home." Check in on it each week; if-then plans worked best when they were reinforced.
Source 8
Set a goal you control
Sessions a week, minutes walked or a lift you want to improve work better than a look or a weight by a date, because you can hit them by turning up (our suggestion, built on the goal-setting trials).
Source 9
Keep a record
A tick sheet on the fridge, an app or a tracker. Look back each week. The NHS says even a checklist on a piece of paper will do.
Enjoy it
Choose what you like
The NHS says exercise should be something you enjoy, or it may be hard to keep it up. Dancing, swimming, a team sport, a walking group, lifting: the best exercise is the one you'll do.
An effort that feels good
Most sessions can be at a pace where you can talk, and a session that leaves you feeling you could have done more is a good one. Harder sessions have their place once the habit is there.
Your reasons
What exercise gives you (sleep, mood, strength for the things you love, time with friends) tends to last longer as a reason than how you look. It's fine to have both.
Make it a habit: your first month, step by step
Our editorial starting point, built on the habit, planning, self-monitoring and enjoyment studies in this guide.
- Pick the days, the time and the place, and write them down.
- Tie it to something you already do, such as straight after work.
- Choose something you enjoy, at an effort that leaves you feeling you could have done more.
- Make starting easy: kit out the night before, bag by the door.
- Keep a tick sheet or an app log, and look at it each week.
- Arrange to go with someone, or book a class, at least once a week.
- Decide your low-day version (the 10-minute session below) and your missed-day rule: go at the next planned time.
- After 4 weeks, review: keep what worked, and change one thing that didn't.

Other people, cues and rewards
Do it with someone
A friend, a class, a club or a walking group gives you company and a reason to turn up. Support from others went with more activity in older adults, and your GP may be able to refer you to a local exercise scheme.
Rewards and temptation bundling
Saving a favourite audiobook or podcast for the gym raised visits by 51% at first, though the effect faded over time. Small rewards help you get going while the habit forms; they don't replace it.
Fresh starts
Gym visits and goal pursuit rise after a new week, a new month or a birthday. A fresh start is a fine day to begin, but the next planned session is better than waiting for one.
Source 23
When you miss a session, or a week
Go at the next planned time
Missing one day didn't undo a habit, and rewarding the comeback raised gym visits the most. Don't wait for Monday, and don't double up to make it back.
Keep a minimum session
On a bad day, do 10 minutes instead of nothing: short bouts were kept up as well as long sessions, and any activity counts. Our 10-minute starter workout is below.
Expect the first months to be the hardest
Most people who drop out do so while building up, so build up gently rather than starting too hard. After a longer break, our getting back into working out guide shows how hard to restart.
Source 20
Common slips
Starting too hard in January and stopping in February; goals about a look or a weight by a date; all-or-nothing rules (an hour or nothing, every day or nothing); training only alone at an unpleasant effort; and no plan for the week after a holiday or an illness (our suggestions).

Low mood
Low mood is the most common barrier, so don't wait to feel like it. Plan something very small, like a 10-minute walk at a set time, and count it as done. That is how behavioural activation, a talking therapy NICE recommends, works. Doing it with other people makes it easier to keep going.
Feeling down for a while
The NHS says if you have been feeling down for a while and do not feel like your usual self, see a GP to discuss your symptoms. Losing interest in exercise along with other things you used to enjoy can be depression; our depression guide has more (our suggestion).
Source 25
If you're thinking about harming yourself
If you are thinking about suicide or can't keep yourself safe, call 999 or go to A&E. For urgent help, call Samaritans free on 116 123, any time, or in England call 111 and select the mental health option. In the US, call or text 988.
Always tired, not just unmotivated
Our suggestion: tiredness that doesn't lift with rest, poor sleep for weeks, or performance that keeps falling are reasons to see a GP, because conditions such as anaemia or a thyroid problem can look like a motivation problem. Adults need 7 to 9 hours' sleep.
Source 29
ADHD
Short, varied sessions, a fixed time, reminders and someone to train with help many people with ADHD (our suggestion); our ADHD guide covers exercise with ADHD.
When exercise becomes a compulsion
The NHS lists spending a lot of time worrying about your weight and body shape, eating very little food, exercising too much, and having very strict routines around food among the signs of an eating disorder, and says to see a GP as soon as you can. Worrying a lot about one area of your body can be body dysmorphic disorder. Beat's helpline in England is 0808 801 0677, and our eating disorders guide has the other numbers.
If exercise or food has started to feel like a punishment or a compulsion, our eating disorders guide covers the signs and where to get help.
Warning signs: when to stop and get help
Stop and get medical help
If you get chest pain or pressure, feel faint or dizzy, are unusually breathless, or your heart races or beats irregularly during exercise, as our plans advise.
Call 999 (911 in the US)
For chest pain that comes on suddenly and doesn't go away, feels tight or like squeezing, spreads to your arms, neck, jaw, stomach or back, or comes with sweating, feeling sick, light-headedness or breathlessness; severe difficulty breathing; someone who faints while exercising; palpitations that don't go away, or come with chest pain, shortness of breath or feeling faint; or a headache that starts suddenly and is extremely painful, especially while lifting or straining, or comes with numbness or weakness, difficulty speaking or loss of vision. The NHS says a bleed on the brain may be more likely when lifting something heavy. Don't drive yourself to A&E.
Soreness or something more?
A dull ache in your muscles for a day or two after something new is normal. Joint pain that's sharp, gets worse during a set or lingers into the next day means switching to the easier option, and seeing a GP or physiotherapist if it carries on (our plans' rule). Our muscle soreness guide has more.
ME/CFS
If you have ME/CFS (myalgic encephalomyelitis or chronic fatigue syndrome), NICE (the National Institute for Health and Care Excellence) advises against general exercise programmes and programmes with fixed step-by-step increases, so don't follow this guide's build-up. Our ME/CFS guide explains why.
Myths
"You need motivation before you start"Mixed evidence
No trial has tested the claim directly, but intentions fail about half the time, while planning, cues and consistent routines get people moving whether or not they feel motivated.
"It takes 21 days to form a habit"Emerging evidence
Middle times were 59 to 66 days, ranging from 4 to 335, and gym-going took about 2 to 3 months. The 21-day figure didn't come from habit research.
"Miss a day and you've blown it"Emerging evidence
Missing one day didn't affect habit formation, and coming back after a missed workout was what the most effective gym programme rewarded.
"No pain, no gain"Emerging evidence
Feeling good during moderate exercise predicted future activity, and an intensity chosen for pleasure raised attendance.
"Motivated people just have more discipline"Emerging evidence
Consistency, simple routines, the setting and enjoyment built the habit in new gym members, and planning and reminders raised visits in 61,293 members.
"Rewards and trackers keep you going for good"Emerging evidence
They help, but the effects faded: the audiobook boost declined over time, and only 8% of gym programmes had effects that lasted. Use them to get going while the habit forms.

Questions people ask
How do I stay motivated to work out?
Rely less on motivation and more on a plan: set days, times and a place, something you enjoy, a simple record and someone to go with. Planning, goals with tracking, and enjoying the session all help people keep going.
How long does it take to make exercise a habit?
Usually 2 to 3 months, with big differences between people: middle figures of 59 to 66 days across studies, anywhere from 4 to 335 days. New gym members needed at least 4 sessions a week for 6 weeks.
Does it take 21 days to form a habit?
No. That figure didn't come from habit research, and studies found it takes weeks to months.
What do I do when I have no motivation to work out?
Do a smaller version rather than nothing: a 10-minute session or a walk at your usual time, and count it as done. Missing one day doesn't undo a habit, and going back at the next planned time matters most.
How can I make myself enjoy working out?
Choose activities you like, at an effort that feels good while you're doing it: that's what predicted people keeping going. Company, music, or a podcast you save for the gym can help too.
How do I stay consistent at the gym?
Same days, same time, same first exercise, and a plan for obstacles, such as a 20-minute home session if you work late. Consistency and simple routines built the habit in new gym members, and if-then plans worked best when people kept them up.
Do fitness trackers help motivation?
On average, yes: they added about 1,800 steps a day across 39 reviews. Use one if it helps; a paper tick sheet works too, as the NHS suggests.
Should I work out with a friend?
If you can, yes: support from others goes with being more active. A class, a club or a walking group counts too.
How do I get motivated to exercise when depressed?
Don't wait to feel like it: plan something very small at a set time and count it as done, which is how behavioural activation, a talking therapy NICE recommends, works. See a GP if you've felt down for a while, and our depression guide has more.
How do I stay motivated to exercise with ADHD?
Short, varied sessions, a fixed time, reminders and someone to train with help many people. Our ADHD guide covers exercise with ADHD in detail.
How do I get motivated to work out in the morning or in winter?
Make the decision the night before: kit out, bag by the door, a short plan. Have an indoor version for dark or wet days. A fresh start such as a new week is a fine time to restart, but the next planned session is better.
Why do I keep losing motivation?
Everyone's intentions fail some of the time: in studies, nearly half the people who meant to be active didn't follow through. It usually means the plan needs to be smaller, more enjoyable or better timed, not that you lack willpower. If tiredness or low mood is behind it, see a GP.
