Familiarity: I've put it through the wringer
Fast delivery as promised. The hand blocks are heavy, come with their own fastening cord and look indestructible. They allow you to do chin-ups, pull-ups and angle your hands any way that is comfortable. You can attach the blocks to a pull-up bar at the gym and make them close together or far apart. The finger holes really do separate the men from the boys.
