Last week, I bought "the Grid," a new type of foam roller than can take more pressure and doesn't break down as easily as other foam rollers. It's also small, unlike most that resemble pool noodles. I've been trying to stretch with it every day for a few minutes. My main goal is to stretch out my IT bands and avoid injury. It seems to be working already. Today, I didn't feel any IT twinges...good news!
