“This is it! This is the year I finally get fit, lose 20 pounds, and stop using my exercise bike as a glorified clothes rack.”
Every year, we bound into January full of great intentions. By February, we’re back on the settee watching re-runs of Friends in a onesie.

Why does this happen? Are we doomed to forever fail at resolutions, or is there a better way?
Fortunately, there are several strategies we can use to build lasting fitness habits which actually stick – without requiring superhuman willpower.
Sustainable fitness habits are key to long-term health and happiness.
But first, let’s look at why it all goes wrong.

Why Resolutions Fail

1. They focus on outcomes instead of identity
Most resolutions focus on what you want to achieve (for example, “I want to lose 20 pounds” or “I want to run a marathon” or “I want to look like Margot Robbie / Ryan Gosling in the Barbie movie”) rather than the type of person you want to become.
Successful goals need to be tied to intrinsic values and identity or you risk falling back into old habits.
Resolutions often fail because they feel like societal expectations (“I should go to the gym”) rather than personal commitments tied to deeper meaning.
I’ll give you two examples:
A) Someone who wants to look a little better for a class reunion in 8 weeks; and
B) Someone who has a child with a disability and wants to be around as long as possible to care for them.
Person A is driven by societal expectations and short-term concerns about how other people view them, while Person B has a deep intrinsic reason to commit to a lifetime of health and fitness.
2. They don’t fit your lifestyle
Resolutions often fail because they aren’t realistic or sustainable within our daily life. They involve setting up behaviours which align with idealised versions of your life, not your actual circumstances.
Of course, you could choose to completely change your lifestyle, but that’s unrealistic for most people and you need to be honest with yourself.
If you enjoy your current lifestyle – for example, regularly eating out and drinking with friends, or binge watching Netflix shows every evening – and have no intention of giving that up, then it doesn’t make sense to want to look like Margot Robbie or Ryan Gosling, or to train for a marathon.
I’m not saying you need to live like a saint, but there are certain non-negotiables and you need to be sure you’re willing to make the necessary changes.
“It doesn’t make sense to continue wanting something if you’re not willing to do what it takes to get it. If you don’t want to live the lifestyle, then release yourself from the desire. To crave the result but not the process, is to guarantee disappointment.”
James Clear, author of Atomic Habits
3. You’re trying to change too much at once
We’re always impatient to achieve our goals, like TOMORROW!!
We dismiss the power of small, incremental changes over time and instead, fall into the trap of making drastic changes all at once (“I’ll work out 6 days a week and cut out all sweets, cakes, crisps, and alcohol”).
We might be able to white-knuckle our way through the first few weeks on the initial wave of enthusiasm, but it’s unsustainable, and when we constantly fail to achieve our overly-optimistic goals, we feel discouraged and give up.
4. Your environment is working against you
Your environment often doesn’t support your desired habits. Do any of these sound familiar?
- Your garage gym is cold, you have to fight through boxes of stored junk to get to the equipment, the treadmill is folded up, and you get frostbite when you pick up the dumbbells.
- There’s a treat cupboard in the house “for the kids”.
- Snack foods are the first thing you see when you open the fridge.
- Your job involves back-to-back Zoom calls with no time between them for movement.
- The glove compartment in your car looks like the sweets section of a supermarket.
5. You’re aiming for perfection
We seem to have this romantic notion that the process of habit change should go without a hitch. When we inevitably slip up, we abandon the goal altogether rather than getting back on the horse the next day.
It’s the, “I ate a whole pizza, had half a cheesecake and ice cream for pudding, and polished off a bottle of wine – and it’s only 10.00am on day 3 of my diet – so everything is ruined!” mindset.
Or, “I missed one workout, I’m pathetic and might as well just quit!” Perfection doesn’t exist and if you’re hoping everything will go smoothly, you’re going to be sorely disappointed.
Understanding these challenges is the first step to building sustainable fitness habits.
8 Tips to Build Sustainable Fitness Habits This Year
“Dare to live the life you have dreamed for yourself. Go forward and make your dreams come true.” – Ralph Waldo Emerson
That’s the bad news out the way. Now for the good news…these proven strategies dramatically improve your chances of becoming the person you want to be this year.
Rather than relying on motivation alone, these tips focus on building sustainable systems and habits that can stick for a lifetime.
1. Focus on the Process

You have very little control over your big outcome goal (”lose a stone”) and how fast it will happen.
To create sustainable fitness habits, focus on small, consistent actions rather than perfection. Focus on achieving specific, consistent actions which you do have control over and will lead you to your goal.
Start by mapping out the process required to get you there, breaking it down into small actions which you do have control over and focus on achieving those consistently.
For example:
- Eat protein with every meal.
- Drink 2 litres of water every day.
- Walk for 15 minutes after dinner every night.
- Strength train twice a week.
- Be in bed by 10.30pm.
Bonus points if you can find someone to help keep you accountable to the process. Find a workout buddy, a supportive friend, or a coach to keep you on track.
2. Build Systems
Develop foolproof systems which make it easy to stay consistent with your process goals. For example:
- Put your workout clothes in your gym bag the night before and place it beside the front door. Keep an extra set in the car or at work for those occasions when you still forget to pick up your bag on the way out!
- Schedule workouts in your calendar app and treat them as important appointments you have to attend.
- Create a repeatable weekly meal plan.
- Fill a large water bottle and drink from it regularly throughout the day.
3. Tie Your Goals to Your Values
Focus on becoming the type of person who naturally embodies the habits you want to achieve.
For example, a busy parent who wants to lose weight might reframe this as, “I want to be the kind of person who prioritises my health so I have more energy for my kids and hobbies.”
Start small habits which align with this identity, like eating a healthy breakfast or walking after dinner.
Now the goal is no longer just about losing weight; it’s to become a person who moves more and eats in a way that supports their desire to live an active life.
4. Embrace Imperfection and Flexibility
As a recovering perfectionist, I can tell you how crippling it is to expect everything to be perfect! Tell yourself at the outset that setbacks are normal and determine to bounce back quickly. Progress – not perfection – is the goal.
If you can get it right about 80% of the time, you’ll be amazed at the results. Even small steps count when working toward sustainable fitness habits.
Cut yourself some slack when it goes wrong too. People who show themselves self-compassion are often more successful when navigating failure. Pay attention to your self-talk and avoid beating yourself up every time you slip up.
There’s a difference between showing self-compassion and giving yourself a permanent get-out-of-jail-free card though! Set a rule for yourself which says never miss twice.
Miss a week of workouts because of work, sickness, or watching too much rugby (like anyone would ever do that…)?
Make sure you turn up next Monday and get right back to it. This is another example of when a workout buddy or coach can be a real asset.
5. Start Small
Starting with a 6-day-a-week gym plan, cutting out all sugar, and eating 200g of protein every day is overwhelming and unsustainable.
Make it so easy at the start that you can’t fail. Begin with small changes and once those stick, layer on new habits, building momentum over time.
- Eat one piece of fruit.
- Eat vegetables with one meal (per day, per week, or per month…whatever it needs to be at the start!)
- Walk for 5 minutes.
- Go to the gym and stretch in a quiet corner.
“Did I show up today?” That’s the win.
Starting small helps lay the foundation for sustainable fitness habits.
6. Celebrate Small Wins

Haven’t eaten anything green since you were force-fed broccoli 20 years ago? Give yourself a high-5 for putting cucumber on your peanut butter sandwich!
Keeping a simple journal is a great way to draw attention to minor changes you might otherwise miss if all you focused on was scale weight or how many times you worked out.
Take note of how you feel and highlight victories like improved energy, better sleep, feeling less stiff, or driving the ball further than your mates up the first fairway.
Use an app or journal to track your habits (the process goals you set above) to create visible evidence of success, no matter how small. This builds momentum and reinforces your identity as someone who is consistent.
Use a habit tracker to monitor daily wins, like checking off every workout or healthy meal. Seeing your streak grow can be highly motivating.
Progress becomes tangible and each checkmark is proof you’re becoming the kind of person who stays consistent with their goals.
You might track things like:
- Did I walk for 30 minutes today?
- Did I eat protein with breakfast?
- Did I have vegetables with dinner?
- Did I go to bed by 10.30pm?
Remember our 80% rule. We’re not looking for perfection! Shoot for 5-6 ticks every week and count that as success.
If you miss a few days, don’t give up and decide you’re a failure; look at why it went wrong and work out how you can make next week a little better.
7. Use “Habit Stacking”

This strategy involves tagging new habits onto routines you’re already doing.
For example:
- A busy professional who is aiming to improve their golf swing might say, “After I change out my work clothes in the evening, I’ll do 10 minutes of mobility exercises for my hips and shoulders.”
- A busy mum who wants to improve their eating habits but struggles with time might decide, “I’ll prep one healthy snack for the day after making my morning coffee.”
Here are a few more examples which show how easy it is to use habit stacking:
- Do 20 press-ups while the shower is heating up in the morning.
- Jog the last 5 minutes of your dog walk.
- After your mid-morning coffee, get outside for 5 minutes before going back to your desk.
- Do 100 calf raises while brushing your teeth at night.
8. Set Up Your Environment For Success

Dr John Berardi, co-founder of Precision Nutrition, states, “If a food is in your house or possession, either you, someone you love, or someone you marginally tolerate, will eventually eat it.”
Setting up your environment for success is key to maintaining sustainable fitness habits. Set up the spaces you spend the most time in to reduce friction and make healthy choices easier.
For example:
- A new parent who struggles to work out at home could create a designated workout area with a yoga mat and dumbbells in the corner of the living room.
- A professional who works from home and is constantly tempted by snacks between Zoom calls could place a bowl of fresh fruit or a jar of nuts on the kitchen worktop so it’s the first thing they see when walking into the room.
- Don’t keep treats – yes, those ones you have “for the kids” – in the house. Allow yourself treats by all means, but go out to get them rather than having them permanently on hand.
- Store the healthy choices at eye level in the fridge.
- Set a “no food in the car” rule.
- Remove clutter from your home gym and make it appealing to train in. Or, better still, go to a commercial gym where the environment is perfectly set up for an effective workout, and where you benefit from the energy which comes from working out with other people.
These strategies will help you build the foundation for sustainable fitness habits that last a lifetime

Most resolutions fail because they focus on outcomes instead of building sustainable habits. They’re often overly ambitious, don’t fit into people’s lifestyles, and lack a solid plan for consistency.
How can I make my resolutions stick this year?
Start by focusing on the process instead of the outcome. Build small, manageable habits that align with your values, embrace imperfection, and set up your environment for success.
What is the 80/20 rule for habit-building?
The 80/20 rule suggests aiming for consistency, not perfection. If you can stick to your habits 80% of the time, you’re likely to see progress without the pressure of being perfect.
How do I get back on track if I miss a workout or slip up?
Don’t let a single slip-up derail your progress. Apply the “never miss twice” rule: if you miss one day, commit to showing up the next. Focus on progress, not perfection.
How long does it take to build a habit?
Research shows it takes around 21 to 66 days to form a habit, depending on its complexity. Start small, stay consistent, and give yourself grace as you adapt to new routines.
How can I set up my environment for sustainable fitness habits?
Make healthy choices easier by decluttering your workout space, placing nutritious snacks at eye level, and scheduling time for your habits. A supportive environment removes friction and boosts consistency.
What’s the best way to celebrate small wins?
Track your progress in a journal or app and reward yourself for consistency. Celebrations can be simple, like acknowledging your effort, treating yourself to a favorite activity, or sharing your success with others.
How do I stay motivated?
Focusing on small wins is essential for building sustainable fitness habits that keep you motivated over time
Do I need a gym to build sustainable fitness habits?
No, you don’t need a gym to start building healthy habits. Activities like walking, home workouts, and bodyweight exercises can all help you stay consistent and achieve your goals.
However, joining a gym has its advantages. A well-equipped gym offers access to a variety of equipment, professional guidance, and a motivating environment which means it can be a valuable resource for developing sustainable fitness habits
