I’ve been using a really firm J Fit foam roller for quite some time now. As I wrote about in this post, using a foam roller is a critical useful tool for increasing blood flow and circulation to your muscles and tissues to promote healing. They can also provide “myofascial release”, which is a technique that results in softening and lengthening of the fascia over your muscles. By focusing the roller on places where you are stiff, sore, or are experiencing reduced flexibility; you can break down unwanted adhesions between the fascia and the underlying muscle tissue. At first the foam roller was pretty painful. But after using it for awhile, I’m used to it and it takes a lot more pressure to work on the knots in my muscles.
