Here are a few options for describing a WordPress post tag named “運動量” (Exercise Volume) in Traditional Chinese, along with explanations to help you choose the best fit:

**Option 1 (Concise and Direct):**

* **Description:** 了解您的運動訓練量。 (Understanding your exercise volume.)

* **Explanation:** This is a clear and straightforward description. It directly translates the tag’s meaning and is suitable for general use.

**Option 2 (Slightly More Detailed):**

* **Description:** 追蹤和分析您的健身訓練的運動量，包含次數、時間和強度。 (Track and analyze the exercise volume of your fitness training, including repetitions, time, and intensity.)

* **Explanation:** This description provides more context. It specifies the context of fitness training (健身訓練) and provides examples of what exercise volume might encompass.

**Option 3 (Focus on the Benefits):**

* **Description:** 掌握您的運動量，提升健身效果，避免過度訓練或訓練不足。 (Master your exercise volume for better fitness results, and to avoid overtraining or undertraining.)

* **Explanation:** This focuses on the positive outcomes of understanding and controlling exercise volume. It highlights the benefits for the reader.

**Option 4 (For a More Technical Audience):**

* **Description:** 衡量和分析運動訓練的總體負荷，包括頻率、時長和強度，以優化訓練計畫。 (Measure and analyze the total load of your exercise training, including frequency, duration, and intensity, to optimize your training plan.)

* **Explanation:** This option uses more technical language (總體負荷, frequency, duration, intensity) and is suitable for a more knowledgeable audience.

**Choosing the Best Option:**

Consider these factors when selecting the best description:

* **Target Audience:** Who are you writing for? General users or fitness enthusiasts?
* **Content of the Posts:** What types of posts will this tag be used for?
* **WordPress Context:** How much space do you have for the description?

For most WordPress setups, **Option 1** or, possibly, **Option 2** will be a good choice because they are generally simple and to the point. However, adjust as needed based on your specific situation. Remember to place it in the “Description” field of the WordPress tag editor for your “運動量” tag.
