I honestly can't recommend Core Tonic enough! I've been attending reformer Pilates classes regularly for the past couple of months, and I've absolutely loved it! The instructors are all so friendly, welcoming and knowledgeable, making every class enjoyable while still giving you a great workout. One of the things I love most is the variety. I actually attended four classes in one week, and not a single session was the same. There's always something different to challenge you, which keeps things interesting and means you never feel like you're just repeating the same routine. The small class sizes are another huge plus. You get plenty of individual attention, and the instructors are brilliant at checking your form and making corrections when needed. It also creates a lovely little community atmosphere, as you start recognising and getting to know the other regulars. I've unfortunately had to take a couple of weeks off due to work commitments, and I can genuinely feel the difference in my body now that I'm not going! If anything, it's made me realise just how much the classes have been benefiting me. Needless to say, I'll be booking myself back in ASAP!

I’ve been attending Core Tonic for 18 months, and love the effects on my body. I’m no slimmer, but am stronger and more flexible. I can squat! Amy and Danielle are super, and whilst the classes can be intense, they get the balance right. The venue is professional and the equipment very good quality.

Core Tonic has completely changed my perspective on exercise! I’ve been going weekly for over a year now & I wouldn’t go anywhere else, all the instructors are so welcoming, helpful & friendly. I’ve seen such an improvement in my flexibility & strength along with a massive change in the way my body feels & looks. It’s all thanks to Core Tonic. If you want a calm, motivating & comfortable environment this is definitely the place for you!

I’ve been going to Core Tonic Pilates for about 18 months now and I absolutely love it. I always look forward to my sessions. The classes allow you to challenge or push yourself as much as you want to, but also offer the opportunity to work at your own pace. Aimee, Jess, Deniz and Daniella are all so friendly and supportive, and they’re always there to offer guidance and make sure you get the most out of the class. Core Tonic also has lovely atmosphere and everyone’s so welcoming. It really feels like being part of a community rather than just going to a class. I would 100% recommend Core Tonic to anyone thinking of taking up Pilates.

Daniella and her team, Aimee, Deniz, and Jessica, are the most exceptional Pilates instructors, I have experienced. I first encountered Pilates more than 10 years ago! They are passionate and enthusiastic about Pilates whereby I look forward to attending classes, even the 06.00 classes they previously scheduled. Which as you can imagine are challenging during the dark winter mornings. Their instructions are clear and easy to follow, but what stands out most for me is the individual care and attention they give. To maximise the efficacy of each Pilates class regarding building and sustaining physical and emotional strengths simultaneously, preventing the potential to sustain injuries and/or exacerbate pre-existing ones. Daniella and her team are incredibly friendly, and welcoming. I can’t praise them highly enough.

I have been going to classes at Core Tonic for the past 6 months and I love them. All the instructors are great and each of the classes are a good all over work out. They are never repetitive so you never get bored.

The most beautiful little studio, clean, calm, always smells good and the girls are lovely. With only 5 beds its a really intimate class where you feel supported all throughout the class.
