What's the difference between people with strong arms and those who practice martial arts?

In fact, there is no difference in the size of strength. It's easy to tell the winner by brute force between people with great strength and people with little strength! But people who have practiced martial arts and practiced it again can turn strength into explosive and destructive power! Explosive power refers to a quick and instant blow, and destructive power refers to the hardness of the blow. Just like thick arms, if there is no speed, the explosive power will be the same as that of people with not very thick arms, because speed makes the power of that stroke increase instantly. Hardness can be imagined as the strength of bones and muscles. If you think your bones and muscles are harder than the other's, the destructive power will be stronger! This is the difference between practicing and not practicing!
