Input:
I had been suffering from Tennis Elbow for nearly a year but at first I would hardly notice it, I could just ignore it and that was it, nearly 5 months ago I started taking swimming lessons and shortly after I started feeling it more and more, until it felt really bad, couldn't even straighten my arm in a natural relaxed way.

So, I decided to look for exercises on the interweb computer and there you have it that using a bar made of a flexible material provides what seems to be the most effective exercise to treat tennis elbow... After some research I decided I would get this one, being a fairly strong guy I went for the blue one and if it felt too hard I'd keep it and get the medium one.

I have done the tennis elbow exercise as recommended, 3 sets of 15 reps daily for only 2 days....

I really hate to sound like a victim of a placebo effect but although I can still feel my tennis elbow condition there, it's not bothering me anymore.

I plan to keep on using this bar and hope to see the problem go away and will update this review.
