Rolflex Link: http://amzn.to/2rUsfFEThe Rolflex is an awesome tool you can use to address chronically painful/right/inflexible area. It's essentially a more targeted version of what you'd get from a high-end sports massage, because you can feel what parts of you need it most. Golfer's Elbow, Tenis Elbow, cramping feet and calves, tight hamstrings, stiff necks, and many other conditions are imported with the Rolflex.
