Bought the blue/heavy one and did the twist and release exercise. Of course it is hard to tell if just this has made by tennis elbow better as I took a lot of rest too, but after using it a few weeks my arm is a lot better. It's for sure worth the try. The best is after your arm is better is to focus on hitting a clean ball. I think especially bad serving and framing backhands are the source for tennis elbow...if you play tennis of course.

How much can go wrong with a rubber stick? The size is good for grabbing, just a bit bigger than a typical tennis racquet handle. The construction seems pretty solid, like it won't fall apart any time soon. The only note that may be useful is that it is relatively stiff when new and softens over the first hundred or so twists. Not surprising if you think about it, but it is sort of the opposite of what you may want, as you usually want to increase resistance as you get stronger. I'm sure any rubber stick will behave this way.

I was very happy with the Thera-Band Flexbar Hand Execiser. The product was delivered promptly, and I am using it in therapy for my tennis elbow, and it has brought some relief.

I purchased the FlexBar to do exercises for my tendonitis in my elbows. I followed the recommended exercises and they both seem to be getting much better plus I can feel the strength in my grip getting better.

After reading an article in the NY Times and watching a You Tube video, I ordered the red (weakest) Flexbar for my longstanding, chronic tendonitis. The exercise is different than any of those outlined in the instruction manual -- be sure to read Dr. Timothy Tyler's method! There was immediate improvement, and by two weeks my pain was gone! I highly recommend the Flexbar!

This bar has been a real life saver. I have been using this for 2 weeks and have seen a huge improvement in my pain relief. I would highly recommend this tool for anyone with tennis elbow. I have actually regained most of my use and I can tell strength is returning to my elbow.[...]

I saw the article in the NYT's and the video how to use on you tube. Having recovered from tennis elbow (TE) I was interested. The product is amazing. The exercise flexes the exact muscles and connective tissue involved in TE. I would reccomend this product.

All the Thera-Band "flexbars are quality products. I bought all three stiffness red(light) green(medium) and blue (heavy), so that I could find the correct level for me to do "tennis elbow" "eccentric contraction" exercises. The green seemed about right for me, 175lb male. I also bought 4 different Cando flexible hand bars: red (light), green(medium), blue(heavy), and black(x-heavy). All four colors felt about the same. To check my sense of feel, I measured the force required to bend the bars to 90 degrees. The forces were as follows: red- 10.2 lb, green- 8.2lb, blue- 11.2lb, black- 10.4lb. The Cando bars appear to be trying to compete with the There-Band "Flexbar". Using my measurements the force to bend these bars 90 degrees are red- 2.3lb, green- 4.3lb, blue- 6.5lb. All the Cando bars are too stiff. It is clear to me that there is no concern about quality by the makers of the Cando bar. How else could one explain that a "light" red bar having about the same stiffness as a black "x-heavy" bar.

Saw this in an article in the New York Times, about a study at Lenox Hill Hospital aimed at simple, inexpensive therapy for chronic tennis elbow. The study was halted early because the results were so dramatic. There's a link to a video showing the exercise. My husband has been using this daily; he had immediate relief of pain which has continued since day one.[...]

good seller, arrived quickly. Too early to say if it is effective for tennis elbow.

This product is easy to use. It can be used to make eccentric exercises easier by deforming the bar and slowly allowing it to go back to normal. The only weakness is that it smells kind of strong when it is fresh. Some plastic/rubber product smell. If you have an open gym, I recommend leaving it out there instead of in the office.

found some specific exercise on utube that was featured in an online health article for tendonitis,works great.

I bought this because I read (and watched a video) about how this could be used as a treatment for tennis elbow. I've been doing the exercise 3 times a day for about a month, and it really helps. I can now straighten my arm without pain, and I'm able to lift some light-weight items without the fear of dropping them. I still have a ways to go, but it sure beats getting shots in an already-painful elbow that send you bouncing off the ceiling!

I haven't used this product, but am going to order one following a NY Times article saying that twisting it is an effective treatment for tennis elbow (and other elbow strains/injuries). The article reported on tests which shows that this is FAR better than conventional treatments for tennis elbow.[...]The NY Times article includes a video showing the specific exercise. Watch it!

Excellent product. Easy to maintain a good grip while training. Provides exercise for muscles used in deep sea fishing, with results that are difficult to achieve with dumbells or other methods.

This product is great for folks who have arm and shoulder problems. It was used as part of my official physical therapy regime after I dislocated my shoulder, and I ordered one for my own use at home, because it was so helpful.

I can not believe how good a work out you can get. This has to be one of the best I have ran across. I am going to order the blue to see how it works.

I purchased this after using the product in physical therapy for a nerve disorder in my arm. I find it useful for keeping my strength up. It is good exercise even if you have no arm problems. I also find it good to roll on my back for a mini-massage.
