Always, always remember that the best way is to add exercise and diet to what people say is not good.
Exercise to lose weight is not local, but whole body. But there are also some local movements that can reshape muscle lines. I recommend you to watch [Muay Thai is fierce]. He answered the questions of losing weight and shaping in detail. At the same time, there are enough video teaching resources online for you to exercise at home or in your dormitory. It is recommended to watch classic foreign tutorials, such as Crazy or px90.
I'm really determined to lose weight and gain muscle. There are ways to do it at any time. Don't delay. Otherwise, I won't go anywhere even if I ask for 10 thousand good ways.
I wish you success!
