I started my training studying all types of dance specialising in Ballet where I trained at the Doreen Bird College of Performing Arts.  This gave me a passion for fitness.

After qualifying in RSA Exercise to music and completing my Fitness Instructor and Fitness Assessment courses, I became qualified to teach Aerobics, Step, Circuits, Body Conditioning alongside Personal Training.

Exercise has always played a major part in my life. I have a passion to keep fit and strong, and to inspire others to exercise. 

My goals and core values echo that of Bethan Fowler, owner and head coach for BFunctional.

I identify with the clear goals of BF vision. There are no egos, everyone is welcome, and everyone encourages each other.

Having suffered a serious illness in 2015 and struggling to gain any serious recovery for 3 years, I found BFunctional.

He enjoys the friendly environment and dedicated personal coaching that has progressed his fitness. Enjoying TRX and ZUU classes in particular.

Constantly fighting middle age the discovery of BFunctional is my mid life crisis, and boy its a good one!

I receive 121 coaching from Bethan at BFunctional, creating a strength program to tailor my needs as a golfer. 

The results have made a huge difference to my golf game, improving my muscular strength, endurance and mind. If at 23 years old I can see the importance of this training to reduce injury and improve performance, could you imagine the impact this could have on the average aged club golfer who would be more likely prone to injuries?

Brandon Delve


Currently playing for Cardiff ADC (academy development squad) striving to play professionally.

The reason I chose BFunctional was due to the guidance and support I was given alongside the patience in order to make me the best I can possibly be. BFunctional instils values and morals to last a lifetime and offer you opportunities that when taken can really set you forward in life. Alongside this I picked up lots of knowledge and the training is exceptional.

Izzy Cooke


Since engaging in Youth TRX classes, I have progressed to regularly captain my school hockey and netball teams.

Aged 13 I am conscious of the need to continually improve my fitness and in particular my core strength.

I am excited about being a BFunctional ambassador and being able to encourage and support others.  Particular my fellow girl students who feel pressure to diet and constantly look good!


The most important investment you can make is in yourself.
