And make sure you are indeed training to concentric failure.

还要确保你是在进行失败的训练。

The other high tide you can think of is being caused by the Earth's centripetal force.

其它高潮你能够想象到是由地球的力引起的。

Now there is a more scientific term known as concentric failure, where you fail to complete the concentric, muscle-shortening phase of a rep without significant compromises to your form or technique.

现在有一个更科学的术语叫失败，指的是你不能在没有对形式或技术出重大妥协的情况下完成一个的、肌肉收缩阶段的训练。

A 2016 study showed that subjects with multiple years of training experience who believed they were pushing to their max, end up making less gains than subjects that were directly instructed to push to concentric failure.

2016 年的一项研究表明，有多年训练经验的受试者认为己已经达到了极限，但最终取得的效果比直接指导进行失败训练的受试者要少。
