Having spent the last 9 months personal training with Stuart at Cross Functional Fitness, I can safely say I would highly recommend him as a PT. He genuinely cares and has great passion for his job. Each session is different, yet tailored to ensure you meet your goals. Sessions are engaging and progress/form is monitored closely throughout. Stuart is very knowledgeable about all things fitness and nutrition related and incorporates and passes this on during sessions

Hi. My name is Stuart Thompson by the way.

I've been able to help hundreds of people get slimmer, stronger, more toned and fitter through my face to face Personal Training service and also remotely through my Online Coaching service.

In 2017 my schedule for face to face sessions became tightly crammed so I became limited in the amount of people I could reach and help. I met many people who said they wanted to train with me but unfortunately lived too far away.

In order to help even more people get in shape without geography or time being limiting factors, I decided to invest in an Online Personal Training service.

I've tested Online Personal Training numerous times using different systems, providing free 3 month trials, follow up questionnaires and client feedback and have perfected this service to the standard it is today.

Although I may not be able to meet you face to face, I use the exact same methodology and strategy to help you achieve your goals as I do with my face to face clients.

I'm very excited to share this with you and I'm excited to help you achieve the goal you're dreaming of.
