If you want to have clearly visible abdominal muscles, you must strictly control your diet and add regular and scientific training to achieve it.
Because if you want to develop abdominal muscles to show muscle shape, you need to adopt a low-calorie diet, which often leads to low efficiency of muscle mass growth, and taking enough protein helps to ensure that abdominal muscles will not shrink with the decrease of body fat, so it is particularly important to increase the intake of protein, and you can eat more chicken breast at ordinary times.
