The reason for kicking is that you are not running in a straight line. This requires you to pay attention to it. When walking and preparing for activities, restrain yourself from walking in a "figure eight" shape and try to walk in a straight line. Regarding the issue of step size, although I don’t know what your reasons are, I am also an athlete who has been training for many years. I can teach you some methods (this is how I trained myself):
1. Pull the leash
Fix one end of the leash to the tree, and tie the other end to your feet, repeat Swing your legs forward.
2. Pull the ligaments
If the ligaments between the hip bones are good, you can naturally maximize your steps.
3. Training
When you usually run, master the rhythm and run with long strides deliberately at first. As time goes by, a conscious stride will naturally form. Finally, based on this, people will increase the frequency.
