Leah Maselli is a certified Pilates instructor and licensed Registered Dietitian with a passion for movement, strength, and helping others feel confident in their bodies.

With ten years as a competitive gymnast and four years as a Division I track and field athlete, Leah learned the power of smart, intentional training and the importance of proper recovery. Pilates became her go-to method for rebuilding strength and mobility after years of high-impact movement.

Leah began teaching Pilates part-time during her undergraduate and graduate studies, continuing while working full-time as a dietitian before eventually making the leap into teaching full-time. Since then, she has taught over 4,000 group reformer classes across franchise studios, maintaining full or waitlisted classes for years. Her teaching journey has taken her to Florida, Western Australia, and California, where she has also led workshops on creative sequencing and elevating the art of teaching.

After years of teaching over 20 classes a week in large group settings, Leah realized the need for a system that helps instructors stay organized, inspired, and confident while managing a full schedule. That experience inspired her to create Pilates by Leah—a platform built to guide and support instructors by giving them all the tools she wished she had when she was in the thick of teaching.

Her teaching style is athletic, intelligent, empowering, and purpose-driven—blending the discipline of Pilates with the freedom of functional strength. Through detailed class plans, practical cueing strategies, and a supportive instructor community, Leah’s mission is to help teachers feel confident, prepared, and passionate about their craft.
