About
Jo En Park
Postural Correction Specialist
Certified STOTT Pilates Instructor
Before transitioning into Pilates, Jo En worked as an educator in both Korea and the UK, completing her Bachelor of Arts in Education at UCL (IOE) and later her postgraduate studies in London. Her years of teaching has shaped her ability to communicate clearly, guide clients with patience and intention and bring a more structured approach to movement.
Her Pilates journey began in her teenage years, when she discovered how mindful movement could ease tension in the body while improving posture and restoring balance. This long-term practice eventually inspired her to pursue professional training with STOTT Pilates by Merrithew™️, where she deepened her understanding of functional strength.
At Her Posture Lounge, her goal is to help clients build strength from the foundations up, as well as to move with confidence in order to experience greater ease in their everyday bodies.
About
Siyun Lee
Postural Correction Specialist
Certified MPA Pilates Instructor · TRX, BOSU & Small Props Training
· Pre & Postnatal Pilates Care
Her journey began in theatre, where she discovered a simple truth: when breath changes, the body changes; and when the body changes, so do emotion and confidence. This insight became the foundation of her work in Pilates.
She has taught in Seoul’s Gangnam district, Bundang, and London, working one-to-one with clients in posture correction, functional strength, pre/postnatal care, and recovery. Her experience in Gangnam’s highly competitive and refined Pilates market shaped her into more than an instructor of exercise—it made her a specialist in transforming posture and body alignment, tailored to each client’s needs.
For her, Pilates is not just exercise, but an art of connection that transforms both body and life. She is with her clients in every breath, helping them unlock their potential and build a body of strength, elegance, and confidence.
