Input:
Started using this for tennis elbow.  There are numerous videos on youtube showing different exercises using this, but it also comes with some material on demonstrating a series of exercises.  I started to feel less pain in my elbow after only a short time using it.  This red color is the next to easiest Flexbar to use and a good starting point to later move up to a higher level of resistance.  It's well made and will last a lifetime of use.  If you do the prescribed exercises consistently, it will help.  Saved me from going the cortisone shot route.
