Question

哪位大神能帮我翻一下这段话？看不懂..谢谢啦

That point in an exercise at which you have so fully fatigued your working muscles that they can no longer complete an additional repetition of a movement with strict biomechanics. You should always take your post-warm-up sets at least to the point of momentary muscular failure, and frequently past that point.
在线翻译我都试过了，效果都不好

在运动中有个临界点，你的肌肉已经达到疲劳的极限以至于它们已经无法完成任何严格生物学意义上的叠加的重复动作。你应该至少在这个短暂的肌肉无力的临界点多做一些后热身动作用以越过那个临界点。
