When stepping, put your whole body center of gravity on the palm of your front foot. When the front of the foot touches the ground, the heel touches the ground first, and then the sole and toes touch the ground. When stepping, your arms must swing naturally, neither too high nor too low. In addition, when stepping, you must cooperate with the pace and breathe rhythmically. Breathe naturally.
Remember not to walk panting.
