Fix your movement. Fix your body. Your body doesn't have to hold you back. Stop leaking, resolve pain, relieve pelvic pressure - or train to prevent it from ever showing up. iCORE Method is a fascia-based pelvic floor and full body training app built by Courtney Virden - a pelvic floor and movement specialist with 25+ years of expertise. Featured in Well+Good, Self, Healthline, and Nike. Most programs train only muscles. iCORE Method trains your whole body - muscles, fascia, and nervous system, feet to head - so results carry over into real life, movement improves, and your body learns to work the way it was designed to. The stability ball is central to almost every session. Training on an unstable surface sends constant feedback through your fascia to your nervous system - triggering whole body adaptation that carries over when you sneeze, lift, run, and move. Training that reduces injury risk and prevents issues from showing up in the first place. Fix Your Movement. Fix Your Body. PELVIC FLOOR AND CORE RECOVERY Two tracks. Every level. RECOVERY TRACK For women dealing with: - Bladder leakage and urge incontinence - Prolapse, pelvic heaviness and pressure - Diastasis recti - Back pain and hip tightness - Pelvic pain and painful intimacy - Constipation and bowel dysfunction - Postpartum weakness - recent or decades ago PERFORMANCE TRACK For women without moderate to severe dysfunction who want to take their training to an advanced level - with greater instability, challenging movements, and full intensity.
