The STRONG System
Transform Your Mindset and Build Your Best Body at Any Age
Book • 2026
Cori Lefkowith's The STRONG System provides a science-backed framework for sustainable fitness by combining mindset shifts, habit design, and strength-focused nutrition.
The book emphasizes tracking and flexible strategies to break the cycle of restrictive dieting and habit overload.
It offers practical systems—such as the habit budget and non-scale victory tracking—to help readers build muscle, improve metabolism, and maintain long-term progress.
Lefkowith draws on her experience as a coach and athlete to give actionable guidance for varied life stages, including perimenopause and aging.
The STRONG System aims to create lasting behavior change through manageable, individualized practices rather than one-size-fits-all programs.
