The GOST-3 shapes match the largest body contours including the glutes, hamstrings, quadriceps and back. This thick and rigid instrument has a more rounded treatment edge compared to the GOST-1 or GOST-2 tools to allow application of firm pressure necessary to reach deeply into soft tissue and large muscle groups. Ideal for treating muscles involved in sciatica, hamstring and quadriceps strains, the IT Band, and mobilizing fascia superficial to the hip flexors. A textured perimeter provides nice grip for one or two-handed use. Specifications: 4.7 ounces, length = 10 inches. Made in the USA. Free shipping!
