Redefining Strength Information

Redefining Strength is an education-driven fitness and nutrition company focused on helping women build strength that supports real life — not extremes, quick fixes, or burnout. Founded by coach, author, and educator Cori Lefkowith, Redefining Strength is known for its no-nonsense, evidence-based approach to training, nutrition, and behavior change. The company challenges outdated beliefs around aging, intensity, and “all-or-nothing” health thinking, replacing them with sustainable systems that evolve with real people and real lives. At the core of Redefining Strength is The STRONG System — a practical framework designed to help individuals build habits, resilience, and physical capability over time. Rather than chasing perfection, the focus is on consistency, skill development, and long-term progress. Through programs, education, and thought leadership, Redefining Strength supports women at every stage of life in reclaiming agency over their health, strength, and confidence — meeting themselves where they are and building forward from there.
