Nudge Theory: Get Fit and Save More Money

Nudge theory can help manage finances by promoting physical fitness, revealing hidden financial benefits.

When it comes to managing our finances, finding effective strategies to save money is a common goal. Surprisingly, one way to achieve financial savings is by focusing on physical fitness. By understanding the mechanics of nudge theory and its application to promoting a healthier lifestyle, we can uncover the hidden financial benefits.

In this article, we will explore the concept of nudge theory, its relevance to physical fitness in Australia, and how it can positively impact your finances.

What is Nudge Theory?

Nudge theory is a concept popularised by Nobel laureates Richard H. Thaler and Cass R. Sunstein. It suggests that small changes in the decision-making environment, known as nudges, can influence people’s behaviour without imposing mandates or restrictions. Nudges aim to subtly guide individuals towards making desired choices that align with their long-term goals.

Choice Architecture

Choice architecture refers to the overall design of a decision-making process. Nudges leverage choice architecture to make certain options more prominent, attractive, or easier to choose. By modifying the environment in which choices are made, nudge theory can steer individuals towards more beneficial behaviours.

Linking Physical Fitness with Financial Health

Physical fitness plays a vital role in overall well-being, and the benefits extend beyond improved health. Adopting a fitness routine can increase productivity, boost energy levels, reduce healthcare costs, and enhance mental well-being. These advantages, in turn, positively impact financial health by reducing medical expenses and improving work performance.

Embracing physical fitness helps individuals establish healthier habits and reduce the risk of chronic diseases. This can result in long-term financial savings by avoiding costly medical treatments, medications, and doctor visits. By focusing on preventive care, individuals can proactively invest in their health, reducing the financial burden associated with illness.

Fitness Benefits of Nudge Theory

Making Exercise More Accessible

Applying nudge theory to physical fitness involves making exercise more accessible and convenient. Fitness nudges can include designing workplaces with standing desks or encouraging the use of stairs instead of lifts; this may even be true if your office is just on the second floor. By adjusting the choice architecture, individuals are more likely to incorporate physical activity into their daily routines, leading to improved fitness levels and potential financial savings in the long run.

Gamification and Rewards

Nudge theory can be leveraged to incorporate gamification elements and rewards into fitness activities. Fitness apps and wearable devices often use features like challenges, achievements, and progress tracking; the app may even be interlinked with the wearable device for more comprehensive fitness monitoring. One example of this is the Apple Watch synchronising with an iPhone’s Apple Fitness app or other third-party health apps to monitor food intake and exercise levels. 

Those elements may prime individuals to engage in regular exercise, driven by the desire to achieve goals and earn rewards. This motivation contributes to improved physical fitness while simultaneously saving money by reducing the need for costly gym memberships or personal trainers.

Healthy Eating Nudges

Nudge theory can also be applied to encourage healthier eating habits. Choice architecture can be modified by placing healthier food options at eye level in grocery stores or installing portion control cues in restaurants. These nudges encourage individuals to make healthier food choices, resulting in improved nutrition and potential financial savings by reducing expenses on unhealthy processed foods or dining out.

Financial Benefits of Nudge Theory

Reduced Healthcare Costs

Embracing physical fitness can lead to a decrease in healthcare costs over time. Proactive management of health through exercise and healthy eating can minimise the need for medical interventions, prescriptions, and hospital visits, thereby saving significant amounts of money in the long term.

Enhanced Work Performance

Regular exercise has been shown to improve concentration, productivity, and cognitive function. By incorporating physical fitness into your routine, you can experience increased mental clarity and focus, leading to enhanced work performance. This can open up opportunities for career advancement, salary increases, or even entrepreneurial ventures, ultimately improving your financial prospects.

Insurance Premium Reductions

Maintaining a healthy lifestyle through physical fitness may also lead to lower insurance premiums. Some insurance providers offer discounts or incentives for individuals who demonstrate healthy behaviours, such as regular exercise or non-smoking habits. By prioritising physical fitness, you can potentially save money on health, life, or disability insurance premiums.

Applying Nudge Theory in Fitness and Finances

Set Attainable Goals

Start small by setting realistic fitness goals that align with your lifestyle and capabilities. This increases the likelihood of adherence and success, reinforcing positive behaviours and motivating you to continue on your fitness journey.

Fitness Apps and Wearable Devices

Take advantage of technology by using fitness apps and wearable devices to track your progress, set reminders, and receive personalised recommendations. These tools can provide the nudges necessary to stay motivated and engaged in your fitness routine.

Create Accountability

Establish accountability measures by sharing your fitness goals with friends, family, or joining fitness communities. Having a support system and regular check-ins can provide the necessary motivation and encouragement to stick to your fitness regimen.

Gamify Your Fitness Routine

Incorporate gamification elements into your workouts to make them more enjoyable. Set challenges, compete with friends, or earn rewards for reaching fitness milestones. 

Certain fitness apps have a variety of challenges all their own to give added motivation. Apple Fitness’ monthly challenge badges, for example, require travelling a minimum set number of kilometres in a day or burning a specific amount of calories every day for 14 days. By making fitness fun and engaging, you are more likely to stay committed and reap the financial and health benefits.

Optimise Nutrition

Pair your physical fitness efforts with a healthy and balanced diet. Incorporate nudge theory principles into your eating habits by organising your pantry and refrigerator to prioritise nutritious options. Plan meals in advance and prepare healthy snacks to avoid impulse purchases or unhealthy food choices.

Track Your Financial Progress

As you prioritise physical fitness, also monitor the positive impact it has on your finances. Keep a record of the medical expenses saved, reduced insurance premiums, or any other financial benefits resulting from your healthier lifestyle. Celebrating these milestones can further motivate you to maintain your fitness habits.


Nudge theory offers a powerful framework for promoting physical fitness and its subsequent financial benefits. By leveraging choice architecture and incorporating small behavioural nudges, individuals can be motivated to adopt healthier lifestyles. Applying nudge theory and prioritising physical fitness may result in achieving a healthier body, mind, and wallet. So, push yourself in the right direction and experience the positive impact on both your physical and financial well-being.
