About Me

I am enthusiastic, pragmatic and supportive of your goals; my role is to help you enjoy exercise and exceed your own expectations.

What Can I Do For You?

Client base: fitness maintenance, goal focused (triathlon), boxing, pregnancy, injury rehabilitation, and general wellbeing. I have been a coach since 2008 and a trainer since 2013.  I am motivated by the benefits that exercise, of all forms, bring to the lives of my clients.  I believe that exercie is a journey and that it is for everybody; with expertise and dedication from the right trainer it can transform a client's quality of life. My clients range in age from early 20s to 80s and I take time to understand exactly what each client wants and needs from the sessions.  I train triathletes who (incorrectly) credit me with having achieved their goals, and I have longterm clients who identify our training sessions as contributing to their lives and their ambition by the work we do in setting, reaching and then achieving new goals. I work face-to-face and online. I am fluent in English and Polish and happy to work in either language.

Tim V. “Jay is a professional. When I started training with him I was obese and now I am so much leaner, healthier and stronger. With his support and knowledge, I achieved goals I never thought I was able to. Changes are so visible that people around me are asking me for advice! I got Jay to thank for it and I highly recommend him.“

Larry C.“With his training regiment, active encouragement, and unwavering support, Jay will over time not only make you faster and stronger physically but more balanced and resilient in mind and spirit as well“

Piotr N.“I found Jarek to be a fantastic trainer, both for gym workouts and outdoor Boot Camp. 

Jarek trained me in bodyweight strength and balance to help my triathlon times. He knew exactly how to get the most from me, and knowing I couldn’t make the gym several times a week, gave me a great set of lower and upper body exercises to do at home between gym visits.

At the Boot Camp Jarek trained a mixed group of us, and was really really good at doing this impossible: making sure no one was left behind but also getting the maximum out of each one of us.
Jarek’s manner is quiet, thoughtful and wise- he really is very effective at making exercises enjoyable and tough. Can’t recommend him enough!“

Amelia N.“Jay is an excellent Pt- he has a really focused and no nonsense approach to training and I’m amazed by the results!“

Graeme B.“Jay’s technical and motivational skills together with diet advice has ensured I exercise effectively to successfully loose weight, gain muscle tone and improve my physical and mental well being. “
