Tan himself has repeatedly said that the main secret to his physique is discipline: he attributes about 70% of his results to nutrition and only 30% to training. His diet is dominated by lean proteins, such as eggs and chicken, while he avoids alcohol and foods with added sugar.

He trains several times a week and includes basic exercises like squats and push-ups. He also maintains a strict sleep schedule and tries not to eat late at night.
