Continue down your spine to hips and buttocks, keeping the nolarola centered and pausing to work out the tender spots. If the nolarola is too painful at any point, you can lessen the pressure by using it on your bed or leaning against a wall.
The buttocks are a major source of muscle tension for many people. Activities such as bending, gardening, skiing, etc., that strain the upper leg muscles, also strain the buttocks. The large muscles of the upper leg (hamstrings and quads) connect with the buttock muscles. Your nolarola is an invaluable tool for reaching stress locked in these large muscles.
