Core³
REDEFINE YOUR CORE.
REFORMER PILATES | INFRARED SAUNA | WELLBEING
At Core³, we believe true wellbeing comes from balance - not intensity alone.
The name Core³ (Core cubed) represents the three essential elements of modern wellness - MOVEMENT, RECOVERY, BALANCE - working together to create lasting strength, clarity, and restoration.
Your Studio
Welcome to Core³. The studio for your Reformer Pilates journey whether you’re a beginner or an advanced practitioner. Core³’s vision is to create a positive and inviting space that is warm, modern and healing – an antidote to the stresses of everyday life. Delivering on Joseph Pilates’ philosophy, our aim is to nurture your body, mind and soul in a welcoming environment, encouraging you to focus on building core strength, increasing flexibility and restoring mindful balance.
Our instructors create an inclusive, friendly and supportive environment, ensuring you have 50 minutes to prioritise your wellbeing.
What is Core³?
MOVEMENT | RECOVERY | BALANCE
1. Movement
At the heart of Core³ is Reformer Pilates - intelligent, low-impact movement that strengthens the core, improves posture, increases flexibility, and supports long-term joint health. Each session is precise, controlled, and designed to build strength from the inside out.
2. Recovery
Our infrared sauna experience supports the body beyond movement. Gentle heat promotes circulation, muscle recovery, detoxification, and deep relaxation - allowing the body to restore, reset, and repair.
3. Balance
The third element is where it all comes together: balance between effort and ease, body and mind. This is where progress becomes sustainable - and wellbeing becomes a way of life.

Space to breathe
Core³ is rooted in Lewes - a town known for its independence and heritage. Surrounded by the South Downs and shaped by a slower, more intentional pace of life, Lewes reflects the same values that define our studio: quality over quantity, depth over noise, and wellbeing that fits seamlessly into everyday life.
Our space is designed as a retreat from the rush - a place to move with purpose, recover deeply, and leave feeling grounded, strong, and restored.
