Narelle is a fully qualified Mat Pilates instructor and has been practicing Pilates for over 10 years. With a Bachelor of Arts and Honours degree in Psychology, Narelle understands the importance of the mind-body connection, a key tenant of Pilates. Her passion for Pilates is evident in her creative classes, teaching good alignment and technique, designed to challenge and encourage her clients to strive for their goals.

Self Defence For Women
Tim’s workshop has provided me a great insight of defending myself in dangerous situations. It was comprehensive and easy to understand. Started with knowing nothing about self defence, I walked away with confidence of protecting myself in just 2 hours.
