Fat in every part of the human body not only provides energy for a certain part, but also provides energy for the whole body. For example, when doing leg exercises, the whole body fat is supplying energy to the body, and it is not just leg fat that is consumed.
What we see is to lose weight by doing local exercise. On the basis of overall fat reduction, local exercise maintains our muscle content and even increases it. Relatively speaking, our local perimeter will become smaller.
