Open gallery Chung Tze Khit took a gamble when he took the $40,000 his father had saved for his university education and bought a Volkswagen Caddy van instead. Open gallery With his father's support, the budding entrepreneur, then aged 23, stocked his van with a workout bench, dumbbells, exercise mats and other gym equipment, and plastered a white decal on the vehicle's window that read: "Singapore's 1st Mobile Gym". Open gallery The 29-year-old now runs Gold's Gym, the largest home-grown chain of personal training gyms, with 17 outlets across the island in places such as Tanjong Pagar, Upper Bukit Timah, Upper Thomson and East Coast. Open gallery He owns and operates one outlet, and manages the other 16 outlets with 10 franchise partners. Open gallery Speaking to Life! at his Upper Bukit Timah outlet, Mr Chung says of that $40,000 helping hand from his father: "I like to think of that money as my education fund that I put to much better use. It wasn't a loan per se. I contribute to the family and make sure my parents lead comfortable lives." Open gallery The tall and fit-looking bachelor, who came to this interview casually dressed in a fitted black polo tee, bermudas and trainers, smiles and tells Life! that his ensemble is his typical work outfit, even for business meetings. Open gallery Mr Chung says he still trains four clients, all of whom are friends who have stuck with him for between four and five years. Open gallery With an eye on expanding his business aggressively this year, he will be launching a spa and wellness arm, called Gold's Wellness Spa, in a few weeks. Open gallery In his leisure time, he hits the beach once a week to play volleyball, collects vinyl records and enjoys taking short holidays in places such as Australia, Bali, Hong Kong and South Korea. Open gallery He never takes long vacations as he does not like to stay away from the business for too long. Open gallery In between working as a freelance personal trainer operating the mobile gym, Mr Chung paid for his university education, obtaining a degree in sports science from Australia's Edith Cowan University via distance learning. Open gallery Not everything was smooth-sailing in business. Mr Chung says it took a failed venture in 2009 to make him realise how he wanted to run his business. Open gallery Today, there are 17 Gold's Gym branches in Singapore; Mr Chung directly manages the Changi branch. Without giving details, he says that "revenue is doubling year on year".
