No, push-ups mainly exercise the muscles of the upper body. If you hold your fist and fingers together, you will exercise the hardness of your fist and fingers, but it will affect the deformation of your hand. For example, if you do push-ups with your fingers, your finger joints will thicken! ! !

As for height, it has nothing to do with it. On the contrary, it can strengthen the bone density of your upper body. Proper nutrition training is only good for your health, not bad. Make more calcium, because if you lack calcium during training, it will have an impact on your health. Athletes will drink some fruit acid drinks during training in order to supplement nutrition, so as not to affect your health and training effect because nutrition can't keep up! ! ! !

Of course, the nutrition here is not just calcium. I will ensure adequate nutrition during training. I can also do 100 push-ups. I am in good health and my height is not high, only 1.75 ~ ~ ~
