**To choose the best description, consider:**

* **The focus of your blog:** Is it fitness training? General health? Sports? Tailor the description accordingly.
* **Your target audience:** Are they beginners, experienced athletes, or a general audience interested in wellness?
* **Character limit:** WordPress might truncate longer descriptions, so keep it reasonably short if that’s a concern.

You can adapt any of these to better suit your specific needs. You can also translate those into English for your own use in the WordPress interface (e.g., “Description for post tag ‘體能'” or “Tag Description: Physical Fitness”).
