Personal Trainer

I work with people online on a one-to-one individual basis. I create personalised training programs for each individual based around their current fitness levels and their specific goals.


My nutrition plans are designed around each individual, based on foods they enjoy in order to achieve their goals whether it be weight loss or building muscle.

Health Coach

I coach people over an 8 week period to build self-confidence and to overcome any bad habits you have, both physically and mentally. 

Client Testimonials

Transformation Picture 1

Well I started this life changing process in September and in the eight weeks I lost a stone and a half. I must say it is a very manageable program but the level of care and support from Kellie was amazing, not only do I feel amazing for the first time in years the health benefits I have are so much more than I could have ever asked for. I have asthma and with the extra weight I was taking my blue inhaler every day and now I only take it when I have a cold. I started at 11 stone 3lbs and I am now at 9 stone 10 lbs and I'm still losing weight. Thank you so much Kellie from the bottom of my heart, I feel amazing.
