If you have time to exercise more every day, you can do a set of actions: lie flat on the bed, put your hands behind your head, lift your upper body with the strength of your waist, and keep your feet still, so keep it for three seconds and do it 20 times until your back is sore! You can do more according to your own situation! You can also reduce your back and practice your hips. Be careful not to eat less and your stomach should not be too bloated! After working for more than half a month, my classmates said that my waist was much thinner. I don't believe it either. I must stick to it. Wish you success! Oh, I forgot to say that it is easiest to lose weight after menstruation. I am a medical student, just like the teacher said!
