If you simply lose weight, your chest will lose weight and it will be very troublesome to recover.

So partial reduction!

My method is to tie plastic wrap on my arms, thighs and abdomen, and then do simple exercise, walk, jump rope, climb the stairs slowly, or go shopping if you don't mind (but you need long pants and long sleeves)

Put on plastic wrap after exercise and sweat locally, which is very effective.

She can be advised to give it a try.
