**Key Considerations When Choosing:**

* **Audience:** Who is reading your blog? Choose language and tone that resonates with them.
* **Blog Content:** Is your blog primarily about fitness? Then a more detailed description might be helpful.
* **Keywords:** Consider relevant keywords that people might search for to find your content (e.g., 健身訓練 – fitness training, 建構肌肉 – building muscle, 健美 – bodybuilding).
* **Character Limit:** WordPress tag descriptions can have limits. Keep the description relatively concise, aiming for clarity.

I recommend choosing the option that best fits your blog’s style and target audience. For most cases, option 2 or 3 would be good choices. Remember to adapt the tone to match your overall blog personality.
