David’s coaching philosophy emphasises that personal training should never adopt a one-size-fits-all approach. While our needs may share similarities, our life circumstances are inherently unique. Therefore, he advocates for a personalised coaching approach that caters to individual goals. This philosophy places great importance on the collaboration between coaches and clients, guiding individuals toward personal growth rather than solely prescribing tasks. According to David, true success in personal training hinges on education and comprehending the underlying reasons behind each task.

“My initial intention was to ease the pain on my left thigh but I ended gaining more benefits than just recovery. Through thorough assessment by Yanxi and Jong, I got to know my fitness level better and uncover certain muscle issues that I was not aware of. Through only one session and implementing warming up and stretching movements post-therapy advised by Jong, I have recovered from thigh pain without recurrence. This should be the medicine free, straight to the root cause and effective therapy that everyone should look for!”
