Have you ever wondered why a marathon runner might struggle to lift heavy weights, or why a champion weightlifter gets out of breath running for the bus? It is because fitness isn't just one thing. Your body has a whole toolkit of different fitness types, and you can train each one like a superpower!
Words to own
- Cardiovascular Endurance
- How well your heart and lungs deliver oxygen to your muscles during continuous exercise.
- Muscular Strength
- The maximum amount of force a muscle can exert in a single effort.
- Muscular Endurance
- The ability of a muscle to keep working over a long period without getting tired.
- Flexibility
- The ability of your joints to move easily through their full range of motion.
- Agility
- The ability to change the direction of your body quickly and under control.
- FITT Principle
- A four-part formula (Frequency, Intensity, Time, Type) used to design and adjust exercise plans safely.
The Engine Room: Health-Related Fitness
Health-related fitness is all about how well your body functions to keep you healthy, energized, and safe in your daily life. It is made up of five main parts: cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. Think of these five components as the foundation of your physical health.
When you improve these areas, everyday tasks become much easier. Walking up steep hills, carrying heavy school bags, and even sitting upright at your desk for a long time require a healthy balance of these components. You do not have to be an elite athlete to benefit from them; they simply help your body run smoothly like a well-tuned machine.

| Point | Health-Related Fitness | Skill-Related Fitness |
|---|---|---|
| Main Purpose | Improves general health, protects you from illness, and keeps your body working smoothly daily. | Helps you perform specific physical tasks, sports, and athletic movements with high precision. |
| Key Elements | Cardiovascular endurance, muscular strength, muscular endurance, flexibility, body composition. | Speed, agility, balance, coordination, reaction time, power. |
| Example Test | The bleep test (cardio) or the sit-and-reach test (flexibility). | The shuttle run (agility) or the stork balance stand test (balance). |
| Everyday Benefit | Walking up stairs without getting tired or carrying heavy groceries easily. | Quickly catching a falling object or dodging someone in a crowded corridor. |
The Action Toolkit: Skill-Related Fitness
While health-related fitness keeps your body working, skill-related fitness helps you perform specific physical tasks with precision. This toolkit includes speed, agility, balance, coordination, reaction time, and power. These are the tools you use when dodging a defender in rugby, balancing on a skateboard, or catching a fast ball.
Anyone can improve these skills with practice. Because your brain and nervous system control these movements, training them involves teaching your muscles to communicate faster and more accurately with your brain. This is why practicing a specific sports skill makes you feel much more coordinated over time.
Testing Your Limits Safely
To find out which areas of fitness you are strongest in, physical educators use specific tests. For example, the multi-stage fitness test (often called the bleep test) measures your cardiovascular endurance. The plank hold is great for measuring muscular endurance in your core, while the sit-and-reach test measures the flexibility of your lower back and hamstrings.
Testing is not about competing with others or feeling bad about what you cannot do yet. Instead, it simply gives you a starting line. By knowing your current level, you can track your personal progress over time and see exactly how your body adapts and grows stronger as you train.
The Magic Formula: The FITT Principle
If you want to improve any component of fitness, you need a smart plan. This is where the FITT principle comes in. FITT stands for Frequency (how often you train), Intensity (how hard you work), Time (how long you train for), and Type (what kind of exercise you do). By adjusting these four variables, you can target specific fitness goals safely.
For instance, if you want to improve cardiovascular endurance, you might increase your Frequency from two to three days a week, or increase your Time from twenty to thirty minutes of jogging. Changing just one letter of the FITT formula at a time is the safest way to avoid injury while helping your body adapt.

Method
What would you do?
Three real situations. Pick a move and see how it plays out — there is no penalty for exploring.
Scenario 1
Aroha wants to improve her running stamina for the school cross-country race next month. She currently runs once a week for 15 minutes.
Scenario 2
Toby is testing his core strength with a plank hold in PE class. He notices his lower back is starting to sag and hurt, but there are 30 seconds left on the class timer.
Scenario 3
Liam wants to get better at dodging defenders in touch rugby. He decides to design a backyard training plan.
Myth-busting corner
MythIf you do not feel incredibly sore and aching the day after a workout, it means the exercise did not do anything.
TruthMuscle soreness is not a measurement of a good workout. Your body can improve and adapt perfectly fine without you feeling sore, and extreme pain usually means you overdid it.
MythYou are either born with coordination and agility, or you are not.
TruthWhile some people have natural talent, skill-related fitness components can be trained and improved by anyone through regular, deliberate practice.
Exam answer that scores full marks
Explain how a netball player could use the FITT principle to safely improve their cardiovascular endurance for an upcoming tournament.
A netball player can improve their cardiovascular endurance by carefully adjusting the FITT variables. First, they can increase their Frequency from training twice a week to three times a week. Next, they should check the Intensity, ensuring they are working at a moderate-to-vigorous level where they can talk but not sing. For Time, they can gradually increase their workout duration from 20 minutes to 30 minutes. Finally, they must choose the correct Type of exercise, such as continuous jogging, swimming, or netball-specific interval runs, to directly target their aerobic energy system. By changing only one element at a time, they will get fitter while avoiding injury.
Why it scores
- Clearly defines and applies all four elements of the FITT acronym.
- Specifies realistic, safe adjustments appropriate for a Year 7 student-athlete.
- Connects the training type directly to the goal of cardiovascular endurance.
