Carol Hall
InstructorCarol has always pursued fitness activities, including swimming, running, strength and aerobic exercise. Like many working mum’s, finding time for herself was always a challenge but she made time to work out, even whilst working full time and bringing up three boys, mainly by co-ordinating her activities with the boys own out of school activities.
After being diagnosed with Crohn’s disease in her early 20’s. Pilates enabled her to maintain a level of fitness and a feeling of control, enabling her to manage the impact of her condition and recover more quickly following surgery or other issues.
Carol hopes to inspire others with their own challenges by showing how fitness - and Reformer Pilates in particular - can help you manage and overcome these difficulties. She says that we can all surprise ourselves with what we can achieve - regardless of our age! - with a bit of determination and self-belief.
“I really enjoyed my first sculpt class with Carol. I didnt feel pressured to do the harder moves, amd she was very reassuring when I was trying new things and was a bit worried about falling. Thanks Carol!”

Marta Romao
InstructorFor Marta, fitness has always been an important part of her life.
After discovering reformer pilates, she was drawn to its mindful, empowering and supportive energy. Her experience inspired me to begin her instructor journey with a goal to bring enthusiasm, empathy and attention to detail into every class she teaches.
Her genuine care for each individual member is reflected in the welcoming and supportive environment she created. Focused on building strength, control, and confidence, expect to feel stronger and more comfortable in your body.
I have attended over 100 sessions and would highly recommend this excellent reformer pilates studio.
When I started I was struggling with complex chronic health conditions and had not been able to exercise for years. Kate and the team tirelessly adapted the classes and the strength and general wellbeing I have achieved since has been hugely transformative.
The classes are varied and the instructors all keep things fun so that the time just whizzes by. I also find the instructors really attentive, meaning I can exercise and challenge myself with safety and confidence.

Lauren Barnes
InstructorLauren originally started Reformer Pilates as a form of physio for her spinal condition, continuing her journey through a complicated pregnancy and she is clear that it has been transformational, making her much stronger in her core and strengthening her spinal muscles.
Reformer Pilates made such a difference for Lauren that she decided to train to be an instructor. Her aim is to hold a safe space for her clients, to help them become stronger and to give them 45 minutes of calm, uninterrupted ‘me’ time.

“I first tried Reformer Pilates about a year ago, back when it was still Ballantyne, and absolutely loved it, but life got in the way. I decided to come back in September 2026, now as Mood Reformer, and I’m so glad I did. Same amazing energy, such a great vibe, and genuinely lovely instructors. I came back shortly after losing my grandma in August, at a time when I really needed somewhere I could feel safe, switch off my thoughts for a while and feel some control over my body again. It turned out to be exactly what I needed. And the bonus? My body looks better, my posture has improved, I feel stronger, and for those 45 minutes, my mind is actually quiet. ❤️ Thank you for creating such a lovely little escape. 🙏🏻❤️”
