He's done good for someone who had his Mum worried because he started walking only when he was 21 months old.

The winner of the Are You Men's Health Enough? contest revealed: "She was afraid that I was never going to walk."

The late bloomer also learnt to swim only when he was 18. Five years later, he took up triathlon and has since taken part in about 30 triathlon races and three Ironman races. Ironman generally covers longer distances. For instance, instead of a Olympic-standard 10km run, it covers a 42km run.

Seah, who has a girlfriend of five years, volunteers to train youth triathletes because he believes "they are the key to our next generation of sporting nation".

Health and fitness tips:

Although it's important to do all forms of exercise, I think cardiovascular fitness is the most important because it benefits the heart which is the engine of the body. Sports like running and swimming count as cardiovascular sports.

Don't set goals that are difficult to attain because that will just cause unnecessary stress. A 30-minute brisk walk, for instance, is good enough if you just want to burn fats.

Where do you usually shop?

At Takashimaya and Paragon, but I don't have a favourite store.

Any beauty regime?

What's your most embarrassing fashion faux pas?

I was in England for my best friend's wedding and felt so under-dressed in a shirt and tie because everyone there was in a suit. I felt like a waiter.

Health and fitness tips:

I don't go to the gym because I find the people there intimidating. So I train at home and do simple weights training.

A lot of people use the excuse of being too busy with work to exercise. But I walk from the train station to my office and that's a kind of exercise too. Sometimes, I walk up the stairs to my flat on the 14th floor instead of using the lift.

Where do you usually shop?

Springfield, Zara, Pull and Bear. Their sizes fit me and the designs are not too loud.

You may know him as one-half of the team that won Amazing Race Asia 2. But Low wasn't always so fit and fab. At 1.68m tall, he used to tip the scales at 90kg when he was 17.

It wasn't until he was 19 that friends from the army convinced him to adopt an active lifestyle. He's been hooked since and now weighs a trim 65kg.

He is also a part-time body combat and pilates instructor.

Health and fitness tips:

Start your day with something healthy. I usually drink a glass of apple, carrot and beetroot juice. It's good for detoxification. I also have pineapple, watermelon and dragonfruit as my breakfast.

Eat in moderation. Having three full and balanced meals will help to maintain your metabolism rate and provide you with the right amount of energy.

Where do you usually shop?

I like shopping in Hong Kong because I'm quite small-built and the sizes there suit me. I don't shop a lot here because I don't have much time. But when I do, I go to places like Zara, Topman and Esprit. I'm not that into high fashion.

Any beauty regime?

I cleanse, tone and moisturise every day.

At 19, he became a personal trainer so he could help others lose weight and is a certified health and fitness instructor.

The 1.8m-tall Wong, who claims that he is "single and unwanted", now weighs a trim 73kg and dabbles in Thai boxing.

Health and fitness tips:

Eating well is very important. You need your protein, carbohydrates and fibre. I try not to indulge in saturated fats.

Keep an open approach to fitness. There's no point in forcing yourself to do a sport that you do not enjoy. What's important is to find like-minded people who can exercise with you and lend you the support you need.

Where do you usually shop?

I don't shop a lot. I sometimes go to Nike because the clothes there fit well and are stylish enough to wear in and out of the gym.
