David Ooi

Rehabilitation Specialist & Personal Trainer



David Ooi (@davidooibjj) is a martial artist with competitive records in both Judo and Brazilian Jiu-Jitsu, the latter of which he is currently Singapore’s national champion. He was working in a very sedentary job with long hours and saw the effect this was having on his health. This led to David deciding that he wanted to pursue his lifelong interest in health and fitness by becoming a Physiotherapist. David is also an active coach in Brazilian Jiu-Jitsu in Singapore. His current fitness goals are to qualify for the 2021 Abu Dhabi Combat Championships. After this, David would like to continue his pursuit of obscure athletic endeavours, by lifting the Dinnie Stones in Scotland.

Having been through the rehabilitation process many times, his strength as a trainer is that he is able to empathise with clients who are going through it now. Getting someone back to being able to live their life normally, being able to get back to doing something they love and making someone stronger is what he love the most about working with my clients.

David's training specialization lies in injury rehabilitation (he is also a practicing Physiotherapist with UFIT Clinic), grip training with highly esoteric training implements, and strength and conditioning for combat athletes – specifically grapplers.
