Why Do Humans Get Cramps After Exercise?

Imagine your muscles are like a group of people holding hands and walking in a line. When you exercise, they all work hard together. Sometimes they get tired or too excited, and then one person pulls their hand back really fast, causing everyone to trip over each other. That’s kind of what happens with muscle cramps. Your muscles get tense, tighten up quickly, and cause pain.
