Everyone - Should foam roll...

Nagging low back or knee pain?
The use of a roller creates "Self Myofascial Release" (SMR) - Its the self controlled version of what I do for you.
”Traditional stretching techniques simply cause increases in muscle length and can actually increase your chances of injury. Self-myofascial release (SMR) on the foam roller, on the other hand, offers safe benefits and breakdown of soft tissue adhesions and scar tissue in fascia. Fascia is a three-dimensional fibrous matrix that interconnects throughout all cells of the body. Fascia surrounds muscles, bones, and joints which gives our body structural integrity and strength. Abnormal fascia can be the leading cause of chronic pain, reduced flexibility and decreased athletic performance.” - Journal of Sports Medicine 2011
A foam roller easily found on Amazon, in your local gym or your local sporting goods seller.
