Movement With Purpose. Coached With Care.

Josie Williams brings a deep movement background to the BFunctional Fitness coaching team, shaped by formal training in ballet, modern, tap and jazz at Doreen Bird College of Performing Arts. After graduating, she spent time working in Canada, where she discovered aerobics, step and body conditioning classes, initially as a way to stay fit, but quickly found a passion for the energy, structure and results that coached fitness could deliver.

On returning to the UK, Josie committed to fitness professionally and qualified as an instructor. Over the years, she has taught a wide range of classes, including aerobics, step, boxercise, spin, circuits and body conditioning, building broad experience across different training styles and group environments. She also went on to become Manager at Dylan’s Health Club at Celtic Manor, further developing her ability to support people with different goals, abilities and starting points.

After taking time to focus on family, Josie returned to teaching and trained with Fitness Wales to qualify in Pilates. It was a natural progression from her dance background, combining movement quality, control, posture and precision. Pilates has now been at the heart of Josie’s work for over 22 years, with a particular focus on Mat Pilates and safe, effective technique.

More recently, Josie has also competed in three HYROX races across relay, women’s doubles and solo formats. This has added another layer to her understanding of functional fitness, resilience and smart training, connecting her technical movement background with the wider performance-focused environment at BFunctional.

Josie’s coaching style is structured, supportive and approachable. She believes exercise does not need to feel intimidating to be effective, and aims to create sessions where people feel coached, encouraged and confident. With clear guidance, consistency and attention to detail, she helps members build strength, move better and develop confidence that carries beyond the gym floor.

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!!
