Introducing

I am an accredited personal trainer who uses a variety of specifically tailored physical exercises and individualised nutrition advice to develop and promote others’ health, well-being and mental capacity with a bespoke personal training and nutrition coaching service.

Qualified across a range of disciplines, and a former teacher, I have fostered a passion for developing individuals over many years. The interaction of the body’s systems, and their reliance upon one another, fascinate me and was a key factor in the establishing of Power of One Fitness as a provider of personal training and nutrition coaching.

A Life-Changing Journey with David and Power of One Fitness Before finding David and Power of One Fitness, I felt completely stuck. At 27 stone, my fitness journey seemed like an impossible mountain to climb. I knew I needed to change, but I didn't know where to start or how to sustain it. That's when I discovered David's online programs, and it has been nothing short of transformative. Thanks to David's expert guidance, unwavering support, and tailored advice, I have successfully lost a significant amount of weight, got fitter and stronger. This achievement is entirely down to his unique and personalised approach. What sets David apart is his commitment to creating a plan that is truly for me. He didn't hand me a generic, one-size-fits-all routine. Instead, he carefully considered my personal preferences, my starting fitness level, and my lifestyle. He curated a plan that I could not only follow, but actually enjoy and stick with long-term. This personalised strategy made all the difference, it turned exercise from a chore into a sustainable part of my life. Perhaps the most valuable aspect has been David's constant presence throughout this journey. He was there at every step, offering encouragement, adjusting workouts as I progressed, and always providing prompt, knowledgeable advice whenever I had a question. He created a supportive partnership that made me feel accountable and never alone, even through an online format. I am fitter, stronger, and more confident than I have been in years. David is more than a PT; he is a fantastic coach and mentor. I cannot recommend him and Power of One Fitness highly enough to anyone who is serious about making a real, lasting change. If you're ready to commit, he will give you 100% and guide you to your goals.

David is an excellent personal trainer. He really helped me understand how to train effectively to get the results I wanted, and the workouts he designed were always fun and motivating. I’ve always had a love–hate relationship with pull-ups, but the programme he created for me made me stronger than I’ve ever been — even compared to when I was rowing! Highly recommend.

David recently provided personal training for my 14 year son to enable a more focused approach for his rugby trials - I cannot recommend David enough! He not only focused on the areas which required attention and practise, he succeeded in gaining the buy in of teenager (not always an easy task!) and most importantly, gave my son the best chance of reaching his goals, and do you know what, he got through!  If anyone want success, then go to David!

David’s been great for the 9 months I’ve been training with him. He set up a personalised  program which helped solve my previous niggling injuries. It’s fun, informative and I’m seeing the results. Highly recommended!

The course David set me up with was perfect. Having trained previously I just needed a kick start to get me back in the gym and it’s certainly done that! If you’re looking for support on your fitness journey I’d highly recommend Power of One!

David at Power of One fitness listened to my needs and built a program to meet my initial needs and then developed it as I got stronger. I am now healthier than ever and look forward to every session!

I am using David's services for last 18 months and it is a great experience. He is very supportive with the training programme and able to advise on many aspects of the workout. And most importantly, I can do my exercises whenever I can in the comfort of my own home.
"David helped me with a training program for a 10k run I did earlier in the year. Right from the beginning, David helped with my running style and also put together an online program which combined my love for circuit training, along with running to get my fitness level up. I not only achieved completing the run, but in a time quicker than I had planned, so I was delighted. I would highly recommend David whether you are looking to achieve a specific fitness target or if you would like an ongoing fitness program, perhaps also twinned with nutrition advice."

"I recently suffered an injury which meant I couldn't do my normal exercise routine. David took time to listen to my concerns and prepared a specialised fitness program to work alongside my physio's directions and enabled me to get back to netball quicker than I hoped."
Katie Lightfoot
"I began having PT sessions with David after realising core and strength work was very much missing from my training, which was at the time predominantly centred on running. The sessions with David have been invaluable, not only have I already improved on speed and strength when running, but I have learnt a lot from his extensive knowledge and experience. This kind of insight will stay with me as I continue on my fitness journey, and not something I could have gained alone. David took time & care to really understand what my goals were and I felt this was a big value add in using Power of One Fitness. Highly recommended."

"David treats me as an individual and gave me great advice on how to stay less stiff, more supple and generally feel better during furlough. Would certainly recommend."
Charlie C
"Went to Power of One Fitness with some specific needs and challenges when it comes to fitness & mobility. David took the time to understand me, my needs and then went on to develop a fitness plan specifically to suit me. If you are looking for knowledgeable support to help you drive the results you are after, then I would recommend that you give Power of One Fitness a try. "
Greg P
"My fitness has now returned thanks to training with David. I can play football again and I feel so much better in every area. The most dramatic affect has been on my diabetes where I'm now taking hardly any tablets compared to when I started. I’m feeling years younger and the sessions with David are always enjoyable as we cover all aspects of training and more."
Alan W
"We did a couples workout with David for 10 sessions and it was truly a great experience. David is a very knowledgeable PT, tailored the exercise to our needs and what we wanted to achieve and regularly checked how we're feeling before and during workouts. We worked super hard during the session and he always kept us motivated and was proud of our progress. He's also very funny and can count in several languages, who knew 🙂 Definitely recommend him to anyone who's looking for a great and experienced PT!"
Nicole H
"An absolutely massive thank you for all of your efforts and interest in helping me with my training. I know I'm not the easiest to motivate, and that it was always the training that suffered first from a lack of motivation or time, or both! However, you were exactly what I wanted in a personal trainer, and why I chose to train with you - someone who understood challenges whether they be time, motivation or mental health based. For me to get back to running 5ks regularly, and the one off 10k this year felt like a massive achievement and am pleased that I have gone into pregnancy feeling fitter and healthier. I would highly recommend you to anyone."
