What Is Stress Urinary Incontinence (SUI)?

Stress urinary incontinence (SUI) happens when small leaks occur during activities like lifting, running, sneezing, or laughing. It’s super common—especially for women who’ve had kids, are over 30, or love high-impact workouts.

While there’s no shame in it, strengthening your pelvic floor is key to improving things long-term. FitKnicks is here to help you feel confident now, while you work on building that strength for the future.
