We’re back! 🩵 After a week behind closed doors, we We’re back! 🩵 After a week behind closed doors, we’re so excited to officially welcome you back into the studio from today. With summer ahead, it felt like the perfect time to give the studio a little TLC. From a fresh lick of paint, to installing air con for those warmer days and a restock of beautiful new equipment from @onyx.wellbeing, every update has been made with your experience in mind. And of course, our favourite addition... our beautiful shutters installed by @thehomeshuttercompany. They’ve completely transformed the space and we couldn’t love them more!🫶🏻 Thank you for your patience while we refreshed the studio. We know a week away from the studio can feel like a long time! We can’t wait to welcome you back into the studio and get back to doing what we love most, helping you move well, build strength and feel your very best. Captured by @marketingandmargaritass 🤳🏻
Week 21: The Reformer Edit by Core Tonic 🩵 Upper B Week 21: The Reformer Edit by Core Tonic 🩵 Upper Body Pulling Series This sequence focuses on building strength through the upper and mid-back, improving shoulder stability and creating stronger, more balanced movement patterns. Moving through: • Wide Row • Underhand Grip Row • Bicep Curl Using the Reformer springs as resistance, these movements challenge control, endurance and coordination while encouraging better posture and deeper connection through the shoulders, arms and back.

Week 20: The Reformer Edit by Core Tonic 🩵 Upper B Week 20: The Reformer Edit by Core Tonic 🩵 Upper Body Series Strength from the shoulders up… with a core challenge built in. The Reformer is an incredible tool for upper body work, using spring resistance to build strength, control and stability through the arms, shoulders, chest and back. By taking these movements into a half kneeling position, we add another layer of challenge. The unstable base requires the core to work harder, improving balance, coordination and pelvic stability while supporting better posture throughout.
If you’ve been to a Core Tonic class before, you’v If you’ve been to a Core Tonic class before, you’ve probably heard these cues many times but there’s a reason we repeat them. In Pilates, the smallest adjustments can completely change how a movement feels and how effectively the body works. From deep core connection to creating length and slowing movement down, every cue is there to help you move with more awareness, control and support. Sometimes it’s not about doing more, it’s about understanding the movement differently. 🩵
