What does it mean that body movement for regulation?

Physical movement processes emotional energy that the body is holding.

Example: You have just left a meeting where a colleague publicly dismissed your work in front of your team. You said nothing in the moment — you smiled, nodded, moved on to the next agenda item. Professional. Composed. But now, twenty minutes later, sitting at your desk, your jaw is clenched, your shoulders are pulled up toward your ears, and your hands are gripping the armrests of your chair as if you are bracing for impact. The anger did not go away because you chose not to express it. It went somewhere — into your muscles, your fascia, your clenched fists. You stand up, walk out of the building, and start walking fast. Not strolling. Walking with purpose, arms swinging, feet striking the ground with force. Within eight minutes, the jaw unclenches. Within twelve, the shoulder tension releases. By the time you return to your desk fifteen minutes later, the anger is not gone — you still disagree with what happened — but the physical charge has dissipated. You can think about the situation without your body screaming at you to fight.

Try this: The next time you notice a strong emotion that is producing physical tension — anger tightening your jaw, anxiety gripping your chest, sadness weighing on your limbs — do not try to think your way through it first. Instead, move. If the emotion is high-energy (anger, anxiety, frustration), choose vigorous movement: a brisk walk, a set of pushups, running up and down a staircase, shadow boxing, or any movement that lets you push hard for five to ten minutes. If the emotion is low-energy (sadness, grief, numbness), choose gentle movement: a slow walk, stretching, or five minutes of simple yoga poses. After the movement, sit for two minutes and notice what has changed in your body. Rate the emotional intensity before and after on a scale of one to ten. Write down both numbers and what type of movement you used. Over time, this log becomes your personal map of which movements process which emotional states most effectively.
