If it's all over, you have to run. When you say kick in the air, it usually lasts more than 30 minutes. Aerobic exercise takes 30 minutes to start burning fat. It is recommended to massage the muscles after kicking in the air and do more stretching exercises, otherwise the legs will become thicker and thicker.
