Height: 1.72m
Weight: 71kg
Exercise regimen: I wake up at 5am and hit the gym before work. I train six days a week for two hours each time and do exercises such as chest presses, pull-ups, weighted squats and bicep curls. I also jog along a park connector twice a week after work.
Diet: I am on a high-protein and low-carb diet. I take proteins such as chicken breast, beef and eggs, as well as protein shakes for a supplement. For carbs, I take oatmeal. I also eat a lot of fruit and vegetables, and drink lots of water. Sunday is my cheat day to indulge in treats such as spicy Sichuan dishes and fast food.

Exercise regimen: I go to the gym six days a week and work out for 1½ hours before work. I am interested in becoming more fit and muscular. I do full-body exercises including leg presses, deadlifts and bench presses. As my working hours are long, I do not have time for other sports.
Diet: I am also on a high-protein and low-carb diet. My diet includes whey protein shakes, chicken breast, fish and nuts. For carbs, I eat some rice with my meals. I also eat fruit and vegetables. I hardly have fried food unless it is a cheat day, which is once a week, or when I am out with friends.
