To increase muscles, you should eat more protein, because protein can make muscles grow, and protein can repair muscles damaged by sports. You can choose milk, protein powder, beef or chicken breast every day.
For practicing abdominal muscles, you can choose a gym, where there are professional coaches and professional equipment, which can get good help. If you exercise by yourself, you can choose to run to reduce fat and reduce body fat content. To exercise the fat in the abdomen and waist, you can choose to roll your abdomen, which is difficult to operate. When you tuck in, you should use your waist to exert your strength.
