Tight Abdomen-randersfc

   Well just go to the gym :)

   It will not happen without training. A press is earned and maintained with a good diet and exercise, but not for the abdomen (doing countless abdominal presses is the biggest stupidity in the world, from personal experience), and heavy basic exercises - squats, deadlifts, shoulder press, etc. Calm down, you will not become muscular if you start training, but on the other hand, if you train hard and with a good diet, you will tighten up and take out the press. I saw my press for the first time in my life at the age of 31, and it didn't happen with abdominal exercises until I fainted, but with a change in training and diet. In general, at your age and given the fact that you have not trained so far, it is quite possible that after you return to school next year from the summer vacation, your classmates will not be able to recognize you. : ) There is plenty of information on the Internet about training and nutrition, especially on YouTube (I recommend the videos of Anelia Terzieva, who is a pretty good specialist in women's fitness). Dig a little, find the right diet for you (there are many diets, but none of them is universal, so you need to find the one that will be easiest for you to stick to), find the right workouts for you, whole body, or upper-lower part, pushing-pulling-legs, etc.) and dare! :) ) and go for it! :) ) and go for it! :)

   Hello, I can recommend you the application of Nike as an exercise, there are all kinds, both for beginners and advanced, they are quite intense and therefore effective, Nike Training says. Apart from that you can do squats, plank, running, abdominal presses, if you do them every day you will tighten for a short period. And as for the way of eating - Atanas Uzunov's diet, it is removed and the fat is cleared, the result is guaranteed. I wish you success!
