Somewhat- if I do 15-20 minutes of hip openers and rolling my back and glute meds, I’m pretty good to go. My stiff-legged deadlift ROM improves significantly. It’s when I inevitably have to sit for a while (in the car in particular) that everything resets. I’ve been bringing my supernova everywhere and basically have it somewhere in my back whenever I’m driving, but it only does so much.
