I have personally used and recommend the use of foam rollers for years to help loosen up targeted muscle areas, manage chronic conditions, prevent injuries and to break up tense fascia and scar tissue. Most people have one somewhere in their home stuck in a corner as after the first or second use, they found it too intense or painful and put it away for safe keeping ! Foam rollers are usually made of hard foam, are 6” in diameter and 3 ft in length. There are a variety of lengths and diameters available these days to fit your body and goals.
