      <h2>为什么核心很重要？</h2>
      <p>核心是维持良好体态与动作稳定的关键。普拉提通过强调呼吸与深层肌群激活，帮助你在<em>日常站立、坐姿与训练</em>中保持更好的身体对齐。</p>
      <h3>入门建议</h3>
      <ol>
        <li>从呼吸开始：尝试<strong>胸廓外扩</strong>而非耸肩。</li>
        <li>慢而可控：注意动作过程中的连贯与专注。</li>
        <li>记录变化：每周拍照或在应用中记录体态变化。</li>
      </ol>
      <p>更多实操可在本应用的「AI体态评估」中获取个性化建议。</p>
