Exercise regimen: I take part in triathlon and Ironman competitions twice a year and maintain a six-day training regimen every week. Each of these sessions can be a 30-lap swim, strength workout in the gym, a 10km to 15km run, or a 40km to 60km ride on my bicycle. On Saturdays, I combine two sessions into one, and sometimes include a 2km open water swim in preparation for competitions.

Diet: I start the day with eggs and coffee, and have salad and a serving of meat for lunch. I usually prepare my own dinner which consists of steamed salmon or chicken and vegetables. I have a low-carbohydrate and high-protein diet and have fruit as snacks.

Exercise regimen: I enjoy short and high-intensity workout sessions of up to 45 minutes, five times a week. These sessions can be cardio exercises like running, brisk walking and sprinting, or body-toning exercises.

I always take the stairs and walk briskly, and it seems like I am always in a rush.

Diet: I have eggs, multi-grain bread, peanut butter and honey for breakfast. Lunch usually consists of steamed chicken or other meat, broccoli and a cup of fruit. I make sure that half the plate is filled with vegetables, one quarter with steamed meat and another quarter with rice. I satisfy my cravings for pastries and fries occasionally, and believe in eating in moderation.
