“Let’s connect body, mind and soul”

Our story

Lilyfit was founded in 2015 as the first online fitness platform in the Middle East. What started as a fitness portal featuring Yoga, Body Toning, and Pilates videos on demand quickly turned into something more.
In September 2021 Lilyfit opened the door to the first Classical Pilates Studio in Belgrade.

Lilyfit is led by founder and principal instructor Ljiljana Duff, a passionate advocate for movement and the benefits that movement can bring to everyone. Lily has over 20 years of experience in the Health and Fitness Industry. She holds a Diploma in Sports Injury Therapies (Australasian College of Natural Therapies – Sydney Australia), is also a qualified Fitness and Personal Trainer (Fitness Institute of Australia), PADI IDC Staff Instructor (Great Barrier Reef, Australia), Contemporary Pilates Instructor (Pilates Moves – Sydney, Australia & Balanced Body – Dubai, UAE) and Classical Pilates Instructor with Pure Pilates Dubai.

She is also certified by the Center for Women’s Fitness by Carolyne Anthony in Pre and Post-Natal Pilates. Lily lived in Australia for many years where she gained most of her qualifications and experience, as well as Spain and UAE where she attended workshops and courses regularly.

She studied the original work of Joseph Pilates from Susanna Foustok (2nd generation teacher) who comes from Jay Grimes’s lineage. Jay Grimes is valued in the Pilates community for his experience, humility, and integrity in maintaining the work of Joe Pilates. Lily also studied from Sandy Shimoda a world-renowned teacher and the owner of Vintage, as well as Gloria Gasperi, a world-renowned teacher and owner of E Motion Pilates school.

Lily is thrilled to be able to share the authentic Pilates work in Belgrade. Lilyfit Pilates Studio is equipped by Contrology Balanced Body Reformer – a unique, classic Pilates reformer, created by Balanced Body with the cooperation with Joseph Pilates’ direct student – Jay Grimes – and his protégé and long-time collaborator.
