Achievements & Credentials

Growing up in a family of martial artists, the love of combat sports was infused in me since young. So when I decided to pick up a combat sport, I wanted to choose a martial art that will be useful to me in the event I have to use it for self-defense, which is one of the reasons why I chose to learn Muay Thai.

Personally, I feel Muay Thai is a practical skill because the techniques being taught can be applied to real life self defense. Most importantly, not only do you learn a skill, you get to keep fit while doing it.

Achievements & Credentials

I fervently believe that overall athleticism is important and continue to work towards being able to lift heavy, run fast, and look good in the process — all simultaneously.

Fitness is an overarching passion and interest of mine, and I go to great lengths to ensure that I am able to devote the necessary time to respective areas of my life. Fitness has also proven to be a very useful tool that I can draw upon when it comes to motivating the men that I lead in the army and for inspiring my peers around me.

Ferocity Rehabilitation

Ferocity believes in the 3 Rs for rehabilitation – “Release, Reboot and Restore”.

Often times, it is common for people to have nagging aches and chronic pains that never seem to go away despite many hours of stretching and massage. Through their experience treating clients, they found that often times there is a compensation pattern that causes an inhibition of certain muscles, resulting in muscular imbalances.

After they identify and release the problematic muscle with a variety of soft tissue release methods and techniques, they will re-boot the brain to teach the body the proper sequence in which the muscles have to fire. A simple series of “homework drills” are then taught to you to enable proper restoration of proper muscle function to the muscles that caused the dysfunction in the first place.

This method of solving dysfunction at its root is a long lasting solution to chronic aches and pains, allowing you to train better, move faster and grow stronger!

Achievements & Credentials


I was the kid that would sit in front of the computer for 12 hours a day before I joined the dragon boat team in Ngee Ann Polytechnic. Since I took part in competitive dragon boating, I have been lifting weights, albeit improperly and have gotten injured multiple times in the process. I became very interested in injury treatment and prevention and started my journey after my National Service.

Understanding and managing my long list of old and chronic injuries has allowed me to better train and treat my clients. Attending courses on different treatment techniques has also broadened my perspective on treatment and training.

My greatest goal is to simplify injury prevention for my clients.

I started my foray into health and fitness in my teens, having picked up bodybuilding from my father in an effort to beef up my underdeveloped frame. Since then, I’ve gone on to further educate myself on all things related to fitness and weight training (including nutrition and rehabilitation). Having personally suffered a laundry list of injuries has given me a better insight into understanding how to get back on track with training post injury.

A large part of my training methods are derived from understanding the body muscle functions and ensuring that movement dysfunction is kept to a minimum. This has allowed me to treat clients with chronic muscle compensation patterns that has enabled them to move and train better with less pain. I am always continually refining my methods as rehabilitative techniques are definitely not exhaustive and every individual is unique in their body’s issues.

My philosophy for training is very simple – educate yourself, train hard, share the results!
