This adjustable foam roller is a really smart upgrade from the usual hard ones. I love that it collapses down, because it takes up way less space and actually fits easily into my backpack. That makes it super convenient to bring to the gym, the court, or even when traveling. Even though it folds down, it’s still firm enough to give solid pressure and work out sore muscles. I’ve been using it mostly on my thighs and arms, and it gets the job done without feeling flimsy.
