I think it depends on the body. It takes a different amount of time for each person. I personally looked for different types of abdominal tightening exercises, I did a lot of repetitions with breaks in between. I trained every other day, sometimes I trained two days in a row and rested once. The effect came after about 2-3 months, but I did not have accumulated fat and I guess to some extent he was lucky. Separately, before I started training often, I did it again, but let's say once a week, when I felt the need to expend some energy and raise my pace of life. On the other hand, I used to do only sit-ups and stretch as soon as I decided I was going to be more serious, my belly tightened quickly, but it took longer for my legs, butt and arms. The point is perseverance. You can consult a fitness instructor, he can certainly prepare a program for you, which will be more correct than anything you can find on the internet. I'm worried about your weight because you're pretty thin for that height. I don't want to film you, I'm not a professional, but I don't think I have a healthy physique and you have to think about gaining weight. When I say weight gain, you should know that I do not mean obesity, but at least a healthy muscle mass.

From person to person there is a difference I trained from a young age with an emphasis on legs and abdominal presses I stopped many years before giving birth and the results are obvious Do not give up the key is a lot of repetitions with short breaks between series Success
