I don’t work for them but one thing that has really helped me is aggressive massage with a Hypervolt.
I use to use a foam roller religiously and honestly it never generated any lasting benefit. The Hypervolt allows me to work on areas on or around the IT band and it appears to last well beyond the treatment.
YMMV but I’ve been super please with the results and definitely feel like I can run at any time without worrying about my IT band flaring up.
