Studio Tarw wasn’t created to be just another fitness studio. It was created to become a part of Cardiff and its community.
Founder Alex Bull spent over a decade immersed in the London fitness industry, coaching at the highest level, learning her craft. Alex saw in Cardiff, an opportunity to build an elite studio environment, like those she had cultivated in London, but smarter, warmer, and more human.
Alex fundraised and built the studio while pregnant, finally opening the doors in July 2025 with her then 10-month old on her hip. At the end of Tarw’s first year in business, Alex became a finalist at the Cardiff Business Awards for the Entrepreneur of the Year accolade, shortly after giving birth to her second child.
In just 18 months, Studio Tarw has woven itself into Cardiff’s sporting and cultural fabric. The team has warmed up thousands at the Cardiff Half Marathon; powered a 24-hour spinathon for Big Moose charity and created moments that live far beyond the studio walls. Tarw doesn’t just host workouts – it shows up for the city.
Inside, the studio is split into three distinct spaces, each with its own entry, purpose, and loyal following.
The Ride Room is electric and high-energy, club-style cycling. The Bootcamp Room is where strength meets structure. The Heated Room, is a sanctuary designed for thiose who understand the power of slowing down.
What ties all three rooms together is the same unmistakable atmosphere. The lights are low. The team is warm, knowledgeable, and genuinely invested. The vibes are high but never intimidating. Studio Tarw is for everyone, and everyone is celebrated. Strength looks different on everybody, and that’s what we champion.

“I began attending Studio Tarw while completing my yoga teacher training and quickly fell in love with the atmosphere. The yoga is beautiful, the pilates is challenging but grounding. Everyone is so encouraging and welcoming, it truly feels like a community. After finishing my teacher training, Studio Tarw was the first place I reached out to because I wanted to give back to the warm, supportive environment they have created and be part of helping others experience that same sense of belonging.” – Erin, 57 Classes
“Tarw’s ride classes are everything I look for in a workout! The instructors bring incredible energy, the music keeps me motivated and singing along from start to finish. The vibes are unmatched, it’s become my favourite way to get an amazing workout while actually having fun. Whether I need to clear my head, sweat off a hangover or boost my mood, these classes never disappoint and the community keeps me coming back!” – Adam, 152 Classes
“I’d never tried anything like bootcamp before joining Tarw so was pretty nervous, but the coaches are so welcoming they talked me through each part of the workout and I could go at my own pace. After trying bootcamp I took part in Tarw’s ‘Hero Week’ and through that made friends for life, the community there is just wonderful!” – Dani, 238 Classes
