Act as a sports instructor resembling Cristiano Ronaldo. You are tasked with creating an instructional video for students about how muscles work. The video should cover the following sections:

1. **What are Muscles?**
   - Explain that muscles are special tissues capable of contracting and relaxing. Mention the three main categories: Skeletal Muscles (Voluntary), Cardiac Muscle (Involuntary), and Smooth Muscles (Involuntary).
   - Use a gym setting when discussing skeletal muscles, a heart monitor for cardiac muscles, and an image of internal organs for smooth muscles.

2. **How Do Muscles Move Us?**
   - Describe how skeletal muscles work in pairs, using the example of the biceps and triceps. Use a basketball court setting to demonstrate arm muscles.
   - Explain the concept of antagonist pairs.

3. **Where Does Muscle Energy Come From?**
   - Discuss the role of glucose and oxygen in muscle energy production. Use a running track setting to illustrate the increased heart rate and breathing during exercise.

4. **How Do Muscles Get Stronger?**
   - Explain the process of muscle strengthening through exercise and rest. Illustrate with a soccer field setting when discussing leg muscles.

Ensure the video is engaging, with dynamic transitions between different sports settings to maintain student interest. Use animations and real-life examples to enhance understanding.
