David

Founder & Transformation Specialist

I left my job in economics to become a personal trainer for the love of teaching and helping people. I started my career in the world’s biggest personal training company in Mayfair where I had the foundations of getting world class results with clients laid down.

Since then I have been mentored and coached by some of the most knowledgeable professionals in our industry and eventually became one of them.

I believe that a transformation is only successful if the client can maintain their result. Forcing someone to eat differently for a while is easy, but it doesn’t last. The real solution is engineering their diet and training around the obstacles of their everyday lives, so instead of forcing a plan on them, this new way of thinking becomes part of their identity.

My goals changed when I realised my clients’ mindset shift brought along positive changes in other areas of their lives too: mental health issues eased, relationships improved, many started to see work challenges in a new light and carried themselves differently. If you look at our testimonials, you will see that the important part is never the amount of weight they lost, but all the other changes that came as a result.

Catalyst was built to help you towards such a total transformation that goes beyond your physique and to give you the tools to enable you to maintain this transformation on your own.

Head of Personal Training

David and I met on the first day of our personal training course in 2017 and have been working alongside each other ever since. We built our friendship, knowledge, and careers side by side, and spent years mastering the craft of helping high achievers get in shape without fitness taking over their lives.

At this stage of my career – approaching my 40s – my focus has shifted toward longevity, mobility, and a more thoughtful approach to training. I grew up between Bhutan and Darjeeling, surrounded by a slower, more grounded pace of life, which shaped the way I coach: calm, precise, and attentive. Clients often say David and I are like yin and yang: we work in perfect sync but bring different energies to the table. Where he brings relentless drive and urgency, I bring empathy, patience, and perspective. Neither works without the other, and this balance is what makes Catalyst so effective.

What sets us apart at Catalyst is attention to detail. We look at the specifics of your life: how you sleep, where you source your food, how much time you have available for training — and we tailor the plan around that. We don’t just show up for your 3 hours a week in the gym, because the magic happens in the 165 hours outside of it. We keep you accountable and adjust plans on the fly when life gets chaotic — because for most of our clients, life is always chaotic. That’s the point. We work with real people with the busiest of lives, not full-time bodybuilder robots.

Getting results is one thing. Getting results that actually stick, and don’t break your life in the process, is where we excel.

Arsia

Head of Online Coaching

I first got into fitness because I grew up as a chubby kid and wanted to make a change for the better.

After getting in shape myself and graduating from King’s College in political economy, I decided to follow my passion instead and go full time into coaching.

When I first started I was expecting clients to do everything perfectly, to my detriment. I quickly had to realise that the game needed to be played differently. For the busiest people in the world the optimal training and nutrition plan becomes the one they can stick to easily. It’s my job to meet the client at their needs and tailor my approach to their lives, not the other way around.

Now, after spending years coaching these clients, my outstanding results with them speak to the effectiveness of my approach.
