Foam rolling: These days, it seems like everybody’s doing it. A growing body of research and an increasing number of bodywork pros — physical therapists, massage therapists, and personal trainers alike — extol the soft-tissue benefits of self-massage for improvements in muscular flexibility and reduction in stiffness (and even pain).To find the best foam rollers for at-home use, we whittled down hundreds of options and enlisted experts (as well as members of our paid tester panel) to spend around 50 total hours kneading and compressing.We discovered that the ubiquitous firm-density foam rollers made of expanded polypropylene (EPP) aren’t much different from one another, at least in terms of the therapeutic benefits they can deliver. But the Amazon Basics High-Density Round Foam Roller stood out from the EPP foam pack as the best basic roller, proving you don’t have to spend a lot to get relief.
