DarrylLicke explained the differences between the different types of rigidity of foam rollers very well.
This is making me wonder what does everyone else do to foam roll their hamstrings? I find that the normal softer foam roller does not do much at all for my hamstrings, and I have some tight hammies! My soft tissue therapist does a good job with them, but I can only afford to visit him once a month or so.
