First of all, you should understand that exhaustion means that you perform a single training action in the same group; Operate the same repetitive action with a fixed weight until you can't do it anymore. This is called exhaustion. Of course, exhaustion training is also a controversial training method, especially for beginners or people who don't repair their hands, because you may suddenly lose your support strength and let barbells or dumbbells hurt muscles and joints, but on the other hand, exhaustion can force you to use more muscle fibers to participate in the output of strength, which will stimulate the contraction of muscle fibers. Through the contraction and destruction of these muscle fibers, in addition, generally speaking, exhaustion can be divided into three forms: technical exhaustion, rhythm exhaustion and endurance exhaustion. As long as one of them is exhaustive training, you should also know the difference before starting exhaustive training.
