Where Biomechanics Meets Better Movement
Hi, I'm Leslie Gale (Timms), a biomechanics-based movement specialist and Pilates instructor. I help people move with greater ease, overcome movement limitations, and build strength through personalized, biomechanics-informed Pilates instruction.
With over 15 years of experience as an outdoor educator, professional rock climber, and guide, teaching movement has long been at the heart of my career. I founded and operated On the Rocks Climbing Guides, delivering climbing education programs on the Niagara Escarpment, and served as a mentor and examiner for the Professional Climbing Guides Institute (PCGI), training and evaluating aspiring climbing guides. These experiences shaped my approach to teaching: helping people develop body awareness, confidence, and a deeper understanding of how they move.
Throughout my climbing career, recurring injuries and persistent movement limitations sparked a deeper interest in biomechanics and the ways our bodies adapt and compensate. As a dedicated student of private Pilates for over 10 years, I've experienced firsthand how individualized instruction can improve alignment, strength, movement awareness, and resilience.
Living with scoliosis and navigating my own injuries has given me a personal understanding of how frustrating it can be when your body doesn't move or feel the way you want it to. These experiences inspired me to pursue professional Pilates training and specialized education in biomechanics, bringing together my passion for movement, teaching, and understanding the body's interconnected systems.
Today, I work with people experiencing pain, stiffness, movement imbalances, or physical limitations who want a thoughtful, individualized approach to improving how they move and feel.
My goal is not simply to guide you through exercises, but to help you better understand your body, build strength and movement confidence, and create meaningful, lasting changes that extend beyond the studio.
