Over 200 Five Star Google Reviews
After signing up for a personal training package, I started with small changes in nutrition along with a structured gym programme from Ross. This programme felt different to any other programme I’ve used before, where tracking calories, macros and weight (which I can get obsessive over!!) was not a priority… consistency was.
It wasn't long before I started fitting into clothes I’ve not been able to wear for a long time. My body was toning up and I was becoming a stronger, healthier version of me. My friends also began commenting on my weight loss too, which felt great! Alongside this, I saw an increase in my strength; managing to add 40kg to my deadlift, perform full press-ups, and include an additional 30kg to my split squat. This boost in performance also helped me return to playing netball weekly, which I absolutely love!

Kubo Priwitzer, Personal Trainer
Kubo is a fitness professional with over a decade of experience. His passion for health and fitness began when he realised that his dream of becoming a professional basketball player wouldn’t materialise. This led him to leave Slovakia and pursue a degree in Sports Science in Scotland.
After graduating, he worked as a gym instructor but found it challenging to give clients the focused support they needed to reach their goals. Motivated to make a greater impact, he started his own business, which continued to grow despite the challenges of lockdowns and restrictions. Eventually, he was invited to join Health by Science—and that’s where he is today.
