7. Don't Change Your Exercise Routine Without Looking at Your Eating Habits

When people decide to become healthier, they often change their diet at the same time as their exercise routine.

That can be helpful, but there's an important distinction between improving food quality and simply eating less.

For example, someone might replace sugary snacks with fruit and include more vegetables in their meals. Those can be positive changes. But if they also start skipping meals, reduce their portions excessively, or avoid entire food groups unnecessarily, they may end up eating too little to support their activity.

Your body needs sufficient energy and nutrients for daily life, exercise, and recovery.

If your goal is to build strength, adequate protein is important for muscle repair and adaptation. Carbohydrates provide energy for physical activity, while dietary fats and a varied selection of foods help meet other nutritional needs.

If weight loss is appropriate for you, a sustainable calorie deficit can help reduce body fat. However, eating as little as possible isn't the goal, and more restriction does not automatically mean better results.

Try focusing on these basics:

Include a source of protein in your meals.
Eat a variety of fruit and vegetables.
Choose carbohydrate sources that help you feel energised and satisfied.
Include healthy sources of dietary fat.
Eat enough overall to support your activity and recovery.

You don't need to eat perfectly to make progress. You need an approach that is nutritious, practical, and sustainable.

8. What Should You Do When You Miss a Workout?

This is where your plan becomes more important than your motivation.

Imagine you planned to exercise on Tuesday, but work ran late. On Thursday, you're tired, and by the weekend you feel that you've already fallen behind.

Rather than trying to make up for everything with an exhausting workout, return to your next planned session.

You can also use a simple backup plan:

Full workout: Your usual planned session.
Short workout: A 10–15-minute version when time is limited.
Recovery option: A comfortable walk or gentle movement when you need something less demanding.

The right choice depends on why you missed the session and how you're feeling. If you're ill, injured, or unusually fatigued, rest or appropriate professional advice may be more suitable than exercising.

The point is to avoid treating every disruption as a reason to quit.

One missed workout is an event. It doesn't have to become a pattern.

Every year, many people tell themselves the same thing: "I'll start exercising in January."

After Christmas, they'll eat healthier, join a gym, lose weight, and finally become consistent with their workouts. The new year feels like the perfect opportunity for a fresh start.

But what happens when work gets busy, the weather is cold, motivation disappears, or the results take longer than expected?

Often, the problem isn't a lack of determination. It's that the plan was never designed to fit real life.

As a personal trainer, I believe you don't need to wait until January to start looking after your health. You also don't need to transform your entire lifestyle overnight.

Research on goal-setting and habit formation offers a more useful approach: start with actions you can repeat, make your goals meaningful, and build a routine that can adapt when life doesn't go according to plan.

Here's how to do that.

1. Is January Really the Best Time to Start Exercising?

The beginning of a new year can feel motivating. It gives us a clear date to reflect on our habits and decide what we want to change. Psychologists sometimes describe this as the fresh-start effect: temporal milestones can encourage people to pursue new goals.

However, a fresh start doesn't automatically create a lasting habit.

In a large study of 1,066 people who made New Year's resolutions, Oscarsson and colleagues (2020) found that 55% of respondents who completed the one-year follow-up considered themselves successful in maintaining their resolutions.

An especially interesting finding was that the type of goal mattered. People with approach-oriented goals reported greater success than those with avoidance-oriented goals.

For example:

Avoidance-oriented goal: "I don't want to be overweight anymore."
Approach-oriented goal: "I want to become stronger, improve my fitness, and feel more energetic."

The second goal gives you something positive to work towards, rather than making your progress entirely about avoiding something you dislike.

This doesn't mean that January is a bad time to start exercising. It means that waiting for a particular date is unnecessary—and choosing a meaningful, achievable goal may be more useful than relying on New Year motivation alone.

Personal trainer's advice: If you already know you want to become stronger or more active, you can start with one manageable habit today. January can be a continuation of your progress, not the beginning of another cycle of starting and stopping.

2. Why Do So Many People Struggle to Maintain Their Fitness Goals?

Think about what happens when someone decides to change everything at once.

They plan to exercise five days a week, stop eating their favourite foods, walk 10,000 steps daily, drink more water, and lose several kilograms in a short period.

The first week might go well because the excitement is new. But the plan can quickly become difficult to maintain alongside work, family responsibilities, social events, and tiredness.

When one workout is missed, the person may feel that they have failed. Instead of adjusting their plan, they sometimes abandon it completely.

This is an example of an all-or-nothing approach: either everything goes perfectly, or the whole plan feels pointless.

A more sustainable approach allows for imperfect weeks.

If you planned three workouts but completed two, you still trained twice. If you missed your usual session because you were busy, you can reschedule it or do a shorter workout.

Progress doesn't require every week to look identical.

The problem with motivation alone

Motivation can help you begin, but it naturally fluctuates. You may feel enthusiastic after watching an inspiring video, then find it harder to exercise after a stressful day.

Instead of asking, "How can I stay motivated every day?" ask:

"How can I make exercising easier to do even when I don't feel motivated?"

That question changes the way you plan your routine.

You might prepare your workout clothes the night before, schedule sessions in your calendar, choose a convenient place to exercise, or arrange a regular class that gives you structure and accountability.

The goal is to reduce the number of decisions you need to make before getting started.

3. You Don't Need to Wait 21 Days to Build a Habit

You've probably heard that it takes 21 days to form a new habit. However, scientific research suggests that habit formation varies considerably between people and behaviours.

Lally and colleagues (2010) studied people who repeatedly performed a chosen behaviour in a consistent context over 12 weeks. The researchers found substantial individual variation in how quickly the behaviour became more automatic. For the participants whose data fitted their model, the estimated time to reach 95% of their eventual automaticity ranged from 18 to 254 days.

In other words, there isn't one universal number of days required to develop a habit.

Some routines may start to feel easier relatively quickly. Others take longer, particularly when they involve changing an established lifestyle or overcoming practical barriers.

This is important because you shouldn't assume that you're doing something wrong if exercising doesn't feel automatic after three weeks.

How to make a fitness habit easier to repeat

Try connecting your workout to something that already happens in your day.

For example:

After finishing work on Monday, I'll complete a 20-minute strength workout.
After breakfast on Saturday, I'll go for a walk.
Before my evening shower on Wednesday, I'll do a short mobility routine.

This creates a clear connection between a familiar situation and a new behaviour.

A missed session also doesn't erase your progress. In Lally and colleagues' study, missing one opportunity to perform the chosen behaviour did not materially disrupt the habit-formation process.

Remember: Consistency matters, but consistency doesn't mean perfection.

4. Start Before January With a Two-Week Fitness Experiment

Instead of making a huge commitment for the entire coming year, use the next 14 days to discover what fits your lifestyle.

Think of it as an experiment, not a test of willpower.

Your goal is to learn which activities you enjoy, when you have time to exercise, and what tends to get in your way.

Week 1: Find your realistic starting point

Choose two or three opportunities to be active.

You could try two short strength workouts and one longer walk, or combine a beginner-friendly class with a couple of walks.

If you're new to exercise, even a 10–15-minute session can be a useful starting point. You can gradually increase the duration and difficulty as your fitness improves.

During the first week, pay attention to:

Which days give you the most time and energy?
Do you prefer exercising in the morning or evening?
Do you enjoy working out at home, outdoors, or in a class?
What usually prevents you from starting?
Which activities leave you feeling good afterwards?

These observations help you build a routine around your real life rather than an idealised schedule.

Week 2: Adjust the plan instead of abandoning it

Review what happened during the first week.

If your planned workouts were too long, shorten them. If you struggled to find time in the evening, try another time of day. If you felt unsure about exercise technique, consider a guided beginner session.

Keep the parts that worked and change the parts that didn't.

At the end of two weeks, you should have a clearer idea of what a realistic routine looks like for you.

Two weeks won't establish every habit or guarantee a particular result. The purpose is to create a workable starting point that you can continue building on.

5. Make Your Fitness Goal Specific Enough to Follow

A goal such as "get fit next year" sounds positive, but it doesn't tell you what to do tomorrow.

A useful goal connects the outcome you want with actions you can actually control.

For example:

Instead of: "I want to lose 10 kg as quickly as possible."

Try: "I will complete two strength workouts each week, walk regularly, and develop balanced eating habits that support my health."

Or:

Instead of: "I want to get stronger."

Try: "I will train my major muscle groups twice a week and record my exercises so I can gradually improve my technique, repetitions, or weights."

The outcome still matters, but your daily and weekly actions are what move you towards it.

Use an if-then plan

Research on implementation intentions suggests that planning when, where, and how you will act can help translate good intentions into behaviour, although the benefits vary between individuals and circumstances (Kompf, 2020).

Try writing a simple plan:

When: Tuesday after work.
Where: At home.
What: A 20-minute full-body strength workout.
If something goes wrong: If I cannot complete the full session, I'll do a shorter version or reschedule it.

This last step is particularly useful. You're planning for obstacles before they happen instead of assuming every week will go perfectly.

6. Why Strength Training Is a Good Habit to Start Now

If improving your health is one of your goals, strength training is worth considering—not just for appearance or weight management, but also for physical function.

Resistance training can help improve muscular strength and physical capacity. It can support everyday activities such as carrying shopping bags, climbing stairs, getting up from a chair, and maintaining independence as you age.

You don't need to begin with heavy weights or advanced exercises.

Depending on your fitness level and available equipment, you could start with:

Chair sit-to-stands or bodyweight squats.
Wall push-ups.
Resistance-band or dumbbell rows.
Glute bridges.
Controlled core exercises.

Start with variations you can perform comfortably with good technique, and progress gradually as you become stronger.

For general health, the World Health Organization recommends that adults work towards 150–300 minutes of moderate-intensity aerobic activity per week, or an equivalent amount of vigorous activity, alongside muscle-strengthening activities involving the major muscle groups on at least two days per week.

These are longer-term public-health recommendations, not a requirement to achieve everything in your first week. If you're currently inactive, start at a manageable level and build up over time.

The best starting workout is one that matches your current ability and gives you room to progress.

9. How to Know If Your Routine Is Working

Don't judge your progress only by your weight or how your body looks.

Those outcomes may matter to your personal goals, but they don't capture every benefit of exercise.

You can also track:

Strength: Are you finding exercises easier or improving your technique?

Consistency: How many of your planned sessions did you complete?

Energy: Do you feel better able to manage your daily activities?

Confidence: Are you becoming more comfortable exercising?

Recovery: Are you allowing yourself enough rest between demanding sessions?

Enjoyment: Have you found activities you actually want to continue?

These measures help you see progress even when physical changes are gradual.

They can also help you identify when a plan needs adjusting. If you're constantly exhausted, dreading every workout, or struggling to recover, you may need a more appropriate training load or additional recovery.

Your 14-Day Healthy Habit Checklist

You don't need to wait for January to begin. Use this simple checklist to take the first step.

Choose two realistic days for strength training each week.
Schedule one or more walks or other enjoyable activities.
Decide what you'll do if you don't have time for a full workout.
Include regular, balanced meals that support your activity.
Track your workouts and notice what makes them easier or harder.
Review your plan after seven days and make adjustments.
At the end of 14 days, decide which habits you can realistically continue.

The aim isn't to complete a perfect challenge. It's to learn how to make healthy behaviour fit your life.

Final Thoughts: Make January Your Next Step, Not Your Starting Line

The new year can be a useful time to reflect on your goals, but you don't need a new calendar to begin taking care of yourself.

Research on resolutions suggests that the way you frame your goals matters. Research on habit formation also shows that routines develop at different rates, and missing an occasional opportunity doesn't mean you've failed.

Start small enough that you can repeat your actions. Make your goals meaningful. Plan for the obstacles you're likely to encounter. Adjust your routine when life changes.

Most importantly, don't wait until you feel perfectly motivated.

You can start with one workout, one walk, or one small change today. Let January be the month you build on your progress—not another month when you promise yourself you'll start.
