Most core answers use the roller as a training tool rather than a massage tool: balance drills, dead bugs and planks on a foam roller. Others cover the obliques (the muscles along the sides of your waist) and the way tight hip flexors and a weak core both show up as lower back strain. The soft front of the abdomen sits over organs, so I keep rolling off it.
