What does it mean that physical channeling of emotions?

Exercise and physical activity are direct channels for emotional energy.

Example: You have been grinding on a problem at work for three hours. A colleague dismisses your proposal in a meeting, and you feel rage flare through your chest — jaw clenching, hands tightening, shoulders lifting toward your ears. You do not send the email you are drafting. Instead, you stand up, walk to the stairwell, and climb ten flights as fast as your legs will carry you. By the time you reach the top, your breathing is heavy, your muscles are warm, and the rage has metabolized into clarity. You still disagree with your colleague. But the physiological urgency — the part that wanted to lash out — has been discharged. Your body processed what your mind could not talk its way through.

Try this: Identify an emotion you are carrying right now — even a mild one. Anxiety, frustration, restlessness, sadness, anything with a bodily signature. Instead of trying to think through it, move through it. Match the physical channel to the emotion: if it is agitation or anger, choose something intense and explosive — a hard run, heavy lifting, hitting a heavy bag, rapid stair climbing. If it is anxiety, choose something rhythmic and sustained — walking, swimming, cycling at a steady pace. If it is grief or sadness, choose something slow and fluid — stretching, yoga, a long walk in nature. Move for at least twenty minutes. Afterward, sit quietly for five minutes and notice what happened to the emotion. Do not analyze. Just notice. Write three sentences describing the before, the during, and the after.
