about DEF

DEF Boxing, established in 2002, is the top boxing gym in Hong Kong and home to Hong Kong's first-ever and most decorated professional boxer, Rex "The Wonder Kid" Tso. Our gym is the best place for you to train, whether you seek glory in the ring or a place to get or stay fit!



Boxing is no longer a violent sport for only the masculinity. In today's health conscious world, boxing is defined as a new lifestyle for everyone -- from professionals such as the fitness-conscious bankers and lawyers, to the cool trendy moms and social elites, to the body-conscious models and celebrities, to even the fun-loving, energetic teenagers!

The Fact is, boxing is ideal for cardiovascular and muscle training as it demands exercise of every muscle in the body. It is training for both mental and physical coordination and reaction. It is strategy and observation of the mind. It is flexibility of body movements. It is detox of daily stress, frustration and mind fatigue. It is stamina building and putting your body to the test - through focus, determination and motivation.
