Add ** note, no more than 140 words (optional) It is not that a single action cannot be used or that the fitness effect cannot be achieved, but that there is a more efficient, more comprehensive and more reasonable training combination, why do you have to stumble on a certain action?You have to know that many chronic strain injuries are obtained in this way, "regardless of physical sensations, regardless of the rationality of the training arrangement, as long as the thin number set in advance is reached". When I saw this question, I was reminded of a scene about three years ago in the autumn when I was on my way to work and passed by a park along the lake. There is an elderly man, he is holding on to the railing to do push-ups, his arm abduction and the angle of the body is much greater than 90 degrees, the pressure on the shoulder joint is very large, and its action speed is relatively fast, then in this case, the stability of the shoulder joint is relatively strong, and the elasticity of the muscles is better, so it is possible not to be injured!Before I went to bed at night, I kept recurring this scene in my head, and I was wondering if I should tell him that the next time I met him, he had a good chance of getting hurt in this way, and he should adjust to do more reasonable movements...Eventually I figured it out: I don't want to tell him, I don't want to interfere with him. It's not because I shouldn't interfere, but when this old man is doing this kind of push-ups, he can only be this amplitude and this intensity for the rest of his life, he can't add more weights, and he can't add more numbers and sets!He can only be "I can do a few and do a few, and when I am tired, I will rest for a while". Then this is within the acceptable range of our body, and our body has this fault-tolerant mechanism!That is, it will not cause damage!
