The Fluid X

About US

Sister team Wendy and Winnie Cheung are serial entrepreneurs who share a love of fitness, startups and swoon-worthy K-drama.

When the pandemic hit and the gyms closed, the sisters went from training at the gym nearly everyday to training at home. Wendy especially missed the community and camaraderie at the gym: a place where nobody talked politics, and everybody supported each other to get stronger on their fitness journeys.

Feeling a bit bored of the usual home workouts, Wendy was introduced to aqua bag training and was immediately inspired and motivated by the versatility, challenge, and fun of the fitness product.

Thus the vision for the Fluid X was born: a community of trainers and fitness enthusiasts who come together for fun and challenging workouts. Together, we can move past our differences and focus on the basics: a healthy, vibrant life.

Catherine Au


Catherine was born and raised in Hong Kong, and has always loved the outdoors and was overall, a very active person. Football, netball and swimming were her favourite sports to play during her primary and secondary school days. She graduated from King George V School in 2020, during the period when the COVID-19 pandemic was at its worst. However, this was a blessing in disguise for Catherine as this is when she really found her passion for health and fitness. Like everyone else, it started with at-home YouTube workouts in the living room, and running outdoors. Once gyms opened up, she took on a proper strength training programme and started making her own health a priority. There were so many benefits she experienced from incorporating regular workouts into her lifestyle. Being self-taught, she was inspired to begin the journey of becoming a Certified Personal Trainer, so that she could share her knowledge and passion with others.

Both her younger brother and cousin have special needs but both still love exercising and outdoor activities. She has a lot of experience in working with those with special needs. She has spent time working closely with Jockey Club Sarah Roe students as well as Talos Foundation, an NGO raising awareness for those with special needs.

Apart from fitness, Catherine is currently studying Design at The University of Hong Kong. She has had a strong interest in the subject since high school and knew that was the path she wanted to follow in the future. After she graduates, Catherine hopes to work in a field where she can combine all 3 passions; fitness, design and helping those with special needs.
