The True Meaning of Fitness

Being physically fit is an invaluable asset, which is why the fitness industry is one of the largest in the world, valued at nearly $100 billion. As health and wellness continue to take center stage in people's lives, physical fitness has become a key aspiration. It is often spoken of as if it were an invisible threshold—exercise enough, and you will be "fit."

While there is some truth to this notion, fitness is a broad and complex term with different definitions depending on context and individual perspectives. Many people reduce fitness to physical appearance, but body composition is just one aspect of the bigger picture.

What Is Fitness?

What does it truly mean to be fit? How can we define fitness in a way that encourages participation and aligns with our lifestyles? What are the different types of fitness?

When discussing fitness, we typically refer to physical fitness. However, fitness extends beyond physical attributes to include skill-related fitness, nutritional fitness, and even mental and emotional well-being. True wellness is not just about how many squats we can do but about our overall ability to function and thrive.

The Core Components of Physical Fitness

Physical fitness can be categorized into four main components:

1. Cardiovascular Fitness

Cardiovascular fitness refers to the body's ability to process and utilize oxygen efficiently. It measures how well the heart and lungs deliver oxygen to the muscles during movement. Activities like running, swimming, cycling, and most sports help develop cardiovascular endurance.

2. Muscular Strength

Strength relates to the amount of force a muscle can exert. It depends on specific muscle fibers that grow in response to resistance training. Developing muscular strength allows us to lift heavier weights and perform physically demanding tasks.

3. Muscular Endurance

This refers to the ability of muscles to sustain effort over time without fatigue. Unlike strength, which focuses on maximum force, endurance is about how long muscles can perform a task. Activities such as long-distance running, cycling, and high-repetition resistance training enhance muscular endurance.

4. Flexibility & Mobility

Flexibility is the ability of muscles to stretch, while mobility refers to the range of motion within a joint. Often neglected, these components are crucial for movement efficiency and injury prevention. Maintaining flexibility and mobility allows for better performance in all other fitness areas.

It's important to recognize that different fitness components interact. Most activities improve multiple aspects of fitness. For example, yoga enhances flexibility, muscular endurance, and strength, while a HIIT session challenges cardiovascular fitness, strength, and endurance.

Defining Fitness for Yourself

At what point can we consider ourselves fit? The answer is highly individual. Fitness levels vary based on age, gender, lifestyle, and personal goals. The NHS recommends that adults between 19-64 engage in at least 150 minutes of moderate-intensity exercise per week or 75 minutes of vigorous activity. However, what is considered "intense" varies from person to person.

For a professional athlete, fitness means qualifying for the Olympics. For a beginner marathon runner, it means completing 26.2 miles. While striving for improvement is great, it's also essential to recognize that fitness is not solely defined by visible abs or gym performance—it is a deeply personal journey.

How to Improve Fitness

Since we all start from different points, our paths to improved fitness will differ. However, there are universal principles that guide fitness progression:

1. Specificity

Your training should align with your goals. If you want to improve endurance, focus on activities like running rather than heavy lifting. Even within a specific fitness domain, targeted training matters—for example, a great runner may not necessarily excel at cycling without specific training.

2. Progressive Overload

Doing the same workout repeatedly without increasing difficulty will lead to stagnation. To improve, you need to continuously challenge your body by adding weight, increasing repetitions, reducing rest time, or intensifying your workouts.

3. Reversibility

Fitness gains are not permanent—if you stop training, your body will gradually return to its previous state. Consistency is key to maintaining progress.

4. Recovery

Improvements happen during rest, not just during workouts. Recovery allows muscles to repair and grow. Beginners often need more rest than advanced exercisers. Overtraining can hinder progress and lead to burnout or injury.

5. Individual Differences

Factors such as genetics, age, and gender influence how we develop fitness. Comparing yourself to others is counterproductive—measure progress based on your own benchmarks.

Finding Your Own Definition of Fitness

Fitness should serve a meaningful purpose in your life, beyond societal expectations or trends. For some, it’s about achieving a specific aesthetic, while for others, it’s about building strength, endurance, or overall well-being. Some people exercise to improve athletic performance, while others simply want to feel more energetic in their daily lives. The key is to define what fitness means to you and set goals that align with your personal needs and aspirations.

Defining personal fitness goals starts with broad aspirations—whether it’s losing weight, increasing flexibility, or running a marathon—and then refining them into actionable steps. This approach helps create a roadmap that makes fitness both achievable and sustainable. Rather than chasing an arbitrary standard, focus on progress that feels meaningful to you.

Starting a fitness journey is often the hardest part. Many people believe they would be fitter if they had more time, a better routine, or easier access to exercise. However, fitness isn’t about finding the perfect circumstances—it’s about making small, consistent efforts that fit into your daily routine. The key is to establish sustainable habits that align with your lifestyle, so exercise becomes a natural and enjoyable part of your day.

Fitness is not just about how much time you spend in the gym or how much weight you can lift. It’s about creating a healthier, more capable version of yourself—one that feels strong, confident, and ready to take on life’s challenges.
