训练原则——渐进性塑身

Rules of Training -- Get in shape gradually

健身是一个渐进的适应过程。如果你尝试增强体适能的速度过快，你会受伤或过度训练。你不能过快推动这个过程。高水平的体适能需要许多小的适应。如果逐渐引入运动压力，你最终会以更低的受伤风险达到更强的身体素质。

Achieving fitness is a gradual process of adaptation. Try to increase fitness too fast and you will get injured or overtrained. You cannot push the process too fast. High levels of fitness represent many small adaptations. If you introduce the stresses of exercise gradually, you will eventually become more fit at a lower risk of injury.
