For me (notice how that's bold) stretching and rolling were not as beneficial to fixing my ITBS issues as strengthening my glutes. My hips and but had gotten so weak. I started adding in glute bridges and the adducter and abducter machines at the gym twice a week and the ITBS in my right knee has gone away. I still stretch and roll but not nearly as much. When I slack on the hips and butt strength the ITBS wants to creep back in
