These could include warming up before starting, using proper form, not pushing beyond one's limits, using safety equipment, etc. As you mention each guideline, provide a brief explanation of why it's important.

4. Demonstration: Now, demonstrate each safety guideline. For example, show how to properly warm up, how to maintain correct form during different exercises, how to use safety equipment, etc. Make sure to perform each demonstration slowly and clearly, so viewers can easily follow along.
