Input:
I had my doubts when this thing arrived.  My right arm was very painful for eight months from a compression injury experienced while weight lifting.  My doctor gave me a wrist brace, pills and a bill.  That didn't help.  I thought, what the heck, try something else, anything!  I followed the Thera-band Flexbar directions and did the exercises for three weeks along with light weight dumbbells.  I had tried the light weight dumbbell exercises previously and that alone did not help.  However, the addition of the Flexbar did.  It took about three weeks to take a constant pain of 5 (out of 10) down to a liveable 1 out of 10.  The first few days of using the Flexbar are painful, but worth it in the end!!!  It's been 9.5 months since I injured my arm and I'm finally back to my weight lifting exericise routine and virtually pain free thanks to the Flexbar.
