It was a fun trial for begginers like me. The coaches are very nice, they explained to me the whole process. And they make sure that I am still within the pace. I am so excited to try boxing next time. Just did strength and conditioning which is really good for a start.

Great and lively atmosphere, coaches and staffs are earnest and friendly! Did the trial class and coach Jo was inspiring and very knowledgeable. Beyond just showing the raw techniques, he could provide in-depth discussions and rationale to the science of boxing. Will definitely come train here again!

Friendly staffs and trainers! (Trainer Jo and Staff Sharifah) Trainer Jo was really encouraging. He knows the theory behind each moves. He was able to carry out the trial class with deft touch. Signed up for a monthly pass!

My first lesson in the gym itself. Gotta admit the class was great with great coaches leading and pushing us to greater height. Frankly it’s not easy as a first timer myself, but I felt a sense of achievement after that. Highly recommend you guys to give it a try, it gonna be worth it.
