Part 1: What is Aerobic Endurance?
Think of your body like a high-performance engine. To keep going for a long time, it needs a steady supply of fuel and oxygen. Aerobic endurance, also known as cardiorespiratory endurance, is your body's ability to do just that! It's how well your heart and lungs can supply your muscles with the oxygen they need to sustain physical activity for an extended period. The better your aerobic endurance, the longer you can play your favorite sport, run, or dance without feeling out of breath.
Fill in the blanks using the words from the word bank below.
Aerobic endurance is all about getting _________________ to your _________________. Your _________________ and _________________ work together as a team to deliver it, allowing you to exercise for a _________________ period of time.
Part 2: The Awesome Benefits!
Building your aerobic endurance has amazing benefits for your whole body. Match the benefit on the left with its correct description on the right. Write the letter of the description in the blank space.
| Benefit | Description |
| 1. Stronger Heart _____ | A. Lets you play and move without getting tired as quickly. |
| 2. More Energy _____ | B. Can take in more air with every single breath. |
| 3. Better Mood _____ | C. Pumps blood around your body more efficiently, like a powerful engine. |
| 4. Healthy Lungs _____ | D. Releases chemicals in your brain called endorphins that make you feel happy. |
Part 3: Get Moving!
Some activities are great for building endurance, while others are designed for short bursts of power. Circle all the activities below that are examples of aerobic exercise. Hint: These are activities you can do continuously for 15 minutes or more!
- Swimming
- Long-distance running
- Cycling
- Sprinting (100-meter dash)
- Dancing
- Soccer
- Heavy weightlifting
- Brisk walking
- Jumping jacks (for several minutes)
- A single high jump
Part 4: Find Your Target Zone
To improve your aerobic fitness, you want to exercise in your Target Heart Rate Zone. This is the 'sweet spot' where your heart is working hard enough to get stronger, but not so hard that it's unsafe. Let's calculate yours!
Step 1: Find your Maximum Heart Rate (MHR)
The formula is 220 minus your age.
220 - 13 = ____________ bpm (beats per minute)
Step 2: Find your Target Zone (60% to 80% of your MHR)
Use your answer from Step 1 to complete the equations.
- Low End of Zone: MHR ______ x 0.60 = ____________ bpm
- High End of Zone: MHR ______ x 0.80 = ____________ bpm
Your goal is to keep your heart rate between these two numbers during an aerobic workout!
Part 5: Your Personal Plan
The best exercise plan is one you'll actually stick with because you enjoy it! Think about what you like to do and set a small goal for yourself.
1. List three aerobic activities you enjoy or would like to try:
- _____________________________________________________
- _____________________________________________________
- _____________________________________________________
2. Set a small, achievable aerobic endurance goal for this week.
Example: "I will go for a 20-minute bike ride three times this week." or "I will play soccer with my friends for 30 minutes on Saturday."
My goal: ____________________________________________________________________________

Answer Key
Part 1: What is Aerobic Endurance?
Aerobic endurance is all about getting oxygen to your muscles. Your heart and lungs work together as a team to deliver it, allowing you to exercise for a longer period of time.
Part 2: The Awesome Benefits!
1. C
2. A
3. D
4. B
Part 3: Get Moving!
You should have circled:
Swimming, Long-distance running, Cycling, Dancing, Soccer, Brisk walking, Jumping jacks (for several minutes).
(Sprinting, heavy weightlifting, and a single high jump are anaerobic exercises – they are short, powerful bursts of energy that don't rely on oxygen in the same way).
Part 4: Find Your Target Zone
Step 1: 220 - 13 = 207 bpm
Step 2:
- Low End of Zone: MHR 207 x 0.60 = 124.2 bpm (or 124 bpm)
- High End of Zone: MHR 207 x 0.80 = 165.6 bpm (or 166 bpm)
Your target heart rate zone is approximately 124-166 beats per minute.
Part 5: Your Personal Plan
Answers will vary based on personal preferences and goals. The important part is choosing activities you enjoy!
