Q How did you get started with weight training?

A I started weight training at Hwa Chong Junior College, when I was with the cross-country team. It was to supplement my training runs and track interval training.

Weight training gave me the power to sprint up slopes and have a good fast finish in a race.

When I realised I was not good enough to be on the national team for track and field, I stopped competitive running and focused on weights to get fit and strong.

The gym is my playground where I can choose from different exercises, and train at different tempos.

Q Don't you need to do cardiovascular exercises like jogging and cycling as well?

A I simply do fast training, which means I keep the rest periods between sets shorter, at around 45 seconds. It's like a cardio workout. My heart rate is maintained at the training zone, which is at 60 to 70 per cent of my maximum heart rate.

Weight training can be used to improve strength, endurance, cardiovascular well-being and injury rehabilitation.

Q What is your diet like?

A I hardly eat meat like pork or chicken and it has been this way since I was six. I can't remember why but I find the taste of meat not to my liking.

Q Do you have tips for those who are trying to maintain their physique?

A Be consistent in your training and diet. Do not stay on a programme that does not match your other real-world commitments like work.

There's no need to do too many repetitions or use very heavy weights. Some people think you have to train every day but you don't to train that often to be healthy. You can be fit but unhealthy and be riddled with injuries from over-training.

To achieve a reasonable level of fitness and strength, you don't have to train more than three times a week but of course, if you want to, you can do so. However, be aware of how your body responds to the training load and how it recovers from it.

Q What is the most extreme thing you have done in the name of fitness or diet?
