LOL, no folks, I'm not talking about sleeping with the baseball still there, but if you can, more power to ya! My gf does not want to wake up with baseballs rolling about, other things are enough.
I just find that if I'm on the floor at the gym or even at home I don't have the patience to wait long enough as to be necessary to get the knot to release. I'm much more patient in bed and the baseball really does the job on those very specific knots...
I wanted to add that I don't know how you're going to get at that IT band specifically. At least not from a MFR point of view. I think that the IT band responds much more to long even stretching from knee to armpit. Hurdle stretch for instance.
