Power of One Fitness has been established by accredited personal trainer David Williams, with the aim of using 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 service.
Qualified across a range of disciplines, and a former teacher, David has fostered a passion for developing individuals over many years. The interaction of the body's systems, and their reliance upon one another, fascinate David and was a key factor in the establishing of Power of One Fitness as a provider of personal training and well-being.
