I want to lose weight, small belly, fast and healthy, tell me how to do it? thank you

Several methods, one is sit-ups, once in the morning and once in the evening, about 100 times each time, as soon as possible. The second is push-ups, 50 at a time, maybe not 50 at a time, but several times. For example, ten at a time, and then rest for half a minute before doing it. Also do it once in the morning and once in the evening. The third is to massage the abdomen, rotating massage, turning 50 clockwise and 50 counterclockwise, twice a day.
