Meet The Founder

Get to know Bethan Fowler, the experience behind BFunctional Fitness, and the coaching standards, energy and philosophy that shape every session on the gym floor.

Led by Experience.
Driven by Standards.

Bethan Fowler is the founder of BFunctional Fitness and the driving force behind the coaching standards, culture and philosophy of the business. With over 25 years immersed in sport, training and coaching, she brings a rare mix of teaching experience, competitive mindset and practical performance knowledge.

Her background began in Physical Education, where she developed the structure, communication and leadership skills that still shape how BFunctional coaches today. From school sport through to high-performance environments, Bethan has always believed that progress comes from consistency, accountability and doing the basics exceptionally well.

Bethan’s own sporting journey spans hockey, athletics, cross country, GB Triathlon Age Group competition, IRONMAN Pro experience and global fitness racing, where she continues to compete and achieve podium finishes. That lived experience gives her coaching a clear edge: she understands effort, pressure, preparation and the standards needed to keep improving.

At BFunctional, Bethan does more than coach sessions. She sets the tone. Her philosophy is simple: be 1% better every day. Through evidence-based training, real-world grit and a no-nonsense work ethic, she helps members move better, perform longer and build confidence that carries beyond the gym.

I’ve spent 25 years training, competing, and coaching, and I still show up every year chasing one thing: to be better than yesterday. So this is a culture of accountability, effort, and shared standards, where hard work is expected and progress is earned.

Brilliant gym with both DEKA and Hyrox classes. I have been doing the DEKA class and today took part in the DEKA mile. Fantastic event, well organised, ran smoothly and the judges were awesome. Would highly recommend and will be back 🥰

I started attending Hyrox specific training sessions at BFunctional in the run up to my first Hyrox in Cardiff. The coaching, technique practice and tips were invaluable and I only wish I had done this earlier! On the day of the event, bumping into some of the other members before and after, and having Bethan shout encouragement to me during the race was so welcome and gave a much needed boost of confidence and support. To be able to join classes and get coaching at that level was the best thing I did in the run up. The excellent guidance and the fun, hard working atmosphere at the gym is contagious! Everyone is friendly, welcoming and encouraging and I really felt part of something special going into the Cardiff event. I plan to continue training to improve for my next Hyrox event. Massive thanks to Bethan 🙏

Beth is a fantastic trainer who is very knowledgeable and professional. She has a great ability to motivate; her classes are hard work but great fun and you always finish the class feeling so much better than when you started. I never thought that when I started going to Beth's classes I would end up entering DEKA and HYROX.

I started going to BFunctional initially for PT sessions with my mum, and it’s honestly been such a positive experience from the start. Beth is an amazing coach — so supportive, motivating and knowledgeable, and she really makes you feel comfortable no matter your fitness level. Training with Beth motivated me to sign up for my very first HYROX, and since then I’ve gone on to complete 4 HYROX events and even run 2 marathons, all while training at BFunctional with her support. The evening classes are brilliant too. Such a friendly and welcoming atmosphere, everyone is so encouraging and the sessions are always challenging but enjoyable. It’s made my training consistent and something I genuinely look forward to every week. Couldn’t recommend Beth enough!

BFunctional has a really motivating atmosphere—no matter your fitness level, you feel comfortable and supported. Since joining, I’ve been much more consistent with my workouts and actually look forward to coming in! I would highly recommend BFunctional to anyone looking for a clean, friendly, and motivating place to train. Bethan leads by example and has a wealth of experience that she shares with us all - she even gets us to compete competitively in Hyrox and Deka events! There’s always a challenge to aim for. 10/10 🌟🌟🌟

I started going to BFunctional classes sometime last year. Bethan encouraged me to try one of her Hyrox classes in Feb and before I knew it, I’d signed up to my first solo Hyrox event (Hyrox Cardiff). In the lead up to the event I attended a variation of different Hyrox classes. The coaching and support from Bethan really helped me to prepare for the event. Bethan is an excellent coach with a real emphasis on safety and ensuring the correct techniques are used. As a coach who competes herself, Bethan not only provides support as a professional but insight and learning from her own experiences as a competing athlete. This level of expertise was invaluable (particularly as a first timer) & I absolutely couldn’t of completed it without Beth & the BFunctional community’s support! If you are looking for somewhere to train to get fit or are looking for a new challenge in a safe supportive environment, I would definitely recommend BFunctional, all abilities are welcomed and celebrated! :)

Training with Beth has been one of the best things I’ve done this last year. I’m fitter, stronger and hitting better Hyrox times thanks to her coaching, support and motivation. She creates such a positive atmosphere in class and somehow makes really hard sessions enjoyable! 🤩 So grateful for all the encouragement along the way!!
