Not at all. Our classes are suitable for complete beginners through to experienced practitioners. Our instructors provide guidance, modifications and support to help you move safely and confidently at your own pace.

Reformer Pilates is a form of resistance-based exercise performed on a specialist reformer machine. It combines controlled movement, strength training and mobility work to improve posture, flexibility, balance and overall body awareness. Reformer Pilates is suitable for a wide range of ages and fitness levels.

Comfortable clothing that allows you to move freely is all you need. For movement classes, we recommend activewear suitable for stretching, strength and mobility work. Layers can be helpful as body temperature naturally changes throughout your session.

Grip socks are mandatory for reformer classes to help improve stability and hygiene. If you don’t already own a pair, you’ll be able to purchase them on-site.

Contrast therapy involves alternating between heat and cold experiences, such as a sauna followed by a cold plunge. This practice has been used for generations to support recovery, circulation, resilience and overall wellbeing. At One Hundred A, recovery is treated as an essential part of the wellness journey rather than an occasional luxury.

Yes. Recovery experiences can be enjoyed independently or as part of a broader movement and wellbeing routine. Whether you visit for movement, recovery or a combination of both, the experience is designed to support how you feel physically and mentally.
