2. In each video, you must:

   • Identify the concentric, eccentric, and amortization phases.

   • Name the major muscles targeted.

   • Provide two technical cues.

   • Demonstrate correct technique.

Examples (to be explained in your video, not written):

1. Concentric, Eccentric, and Amortization Phases:

   • "During the squat, the eccentric phase occurs as you lower down, the amortization phase is the brief pause at the bottom, and the concentric phase is when you push back up to standing."

2. 在每个视频中，你必须：

   • 说明向心、离心和弹性三个阶段。

   • 说明主要目标肌肉。

   • 提供两个技术提示。

   • 展示正确的技术。

示例（这些内容必须在视频中解释，而不是书面形式）：

1. 向心、离心和弹性阶段：

   • “在深蹲时，离心阶段是你下降的过程，弹性阶段是在底部的短暂停顿，向心阶段是你重新站起时的过程。”
