Review: Great for forearms - Started with green, have moved on to blue. I do four exercises- twisted 180 degree clockwise and CCW, bending up into a U, and down into an arc, holding all four in position 30 seconds. Short, easy, do it any time. Surface has striations for good grip. Have increased forearm muscles and mad a significant different in my grip and arm strength. Actually the four exercises will stress arms and shoulders building them to. A really satisfying exercise….

## Questions & Answers

**Q: What’s the difference between the old version vs the new version? Thanks**
A: I don’t know. I have this one and I love it!!!

**Q: Is it okay to do more than 3 sets of 15 reps for golfer's elbow?**
A: Yes I was doing a minimum of 10 sets a day. I had sever golfers elbow. 3 tears in the tendon for 2 years. After 3 months of those it was gone. I also had to completely stop working out and using my arm while I was doing the exercises.  It will give you some good callouses though doing that many sets. Worth it

**Q: Is this product useful for wrist tendonitis?**
A: I think so. I bought this for some golfer’s elbow, but had some nagging off-and-on wrist issues that have also gone away.  Just make sure you get a heavy enough band that it can generate enough tension to effectively stretch things out. FWIW, I started with the green, then switched to the blue when I was strong enough and that’s when the tendinitis really started to clear up. Good luck!

**Q: what color flexbar do you use?**
A: I purchased both the blue and green.  The blue was too much much resistance when I first hurt my arm and immediately after surgery.   That is when I used the lower resistance band.  I would recommend getting two difference colors.

Great for tennis elbow. Bee using these for awhile. Started with the weakest have now made it to blue. Arms are better than they have been in years

### ⭐⭐⭐⭐⭐ INCREDIBLE!!!
*by C***L on October 11, 2017*

This product is amazing. Had several cortisome shots followed by (30 days later) PRP. Extremely painful those were. The pain went away, but with a little activity the pain would come back. I tried EVERY kind of brace, cold and hot packs, massages, nothing helped. I was hurting in both elbows. Went to OTs, nothing helped. I couldn't brush my pain without pain. Then I found the flex bar. I bought the red one first. It did wonders. I was afraid to do almost anything fearing that the pain would come back. It worked great but seemed like the rubber loosened up or got weaker in strength. I had great results. I couldn'the believe it. I was pain free for awhile. Then the pain came back. I bought the blue one. It was way too wide. You need monsters paws for this one. And it's so thick that it's tough to get a workout with it. Then I bought the green one. It fits just right. The strength required is normal. It probably fits most guy's hands. I'm able to hit golf balls now. I could never do that before with the pain. The pain does come back. Not to the previous intensity bUT it's there. I pull out my green flex bar and let it do its magic. I have recommended this to at least eight people. They all love it. My father and his golfing partner for over 40 years have had tennis elbow for over 30 years. Not anymore. They golf pain free now. They were skeptics for a long time. I kept telling them. They kept refusing. Then my pops broke down and tried it. He loved it. His friend denied it for almost a year but saw my father was happy after swinging his clubs. Now he too is a believer. They are able to play tennis without pain, too. The pain will probably come after playing sports or lifting heavy stuff. All you have to do is pull out the flex bar and person the Jacob''s twist. My buddy is an OT. He says, "we have those, they're OK. Ha! It takes away business from him. Probably my best purchase from Amazon. And that says a lot.
