Achieving flat abs, also known as abdominal definition or a six-pack, requires a combination of diet and exercise. Six-pack abs are the result of having low body fat and well-defined abdominal muscles.
A lean diet that is low in calories and processed foods is essential for reducing body fat. Eating plenty of fruits, vegetables, and whole grains will help you feel full and satisfied while consuming fewer calories. Additionally, regular exercise, including both cardiovascular activity and resistance training, is necessary for building and toning the abdominal muscles.
