Yes4All Flex Bar, Elastic Fitness Bars with Strong Fiberglass & TPE Material, 2in1 Functional Exercise Bar, 9.5 inch Comfortable Grip, High Frequency Vibration Training, Strengthen Muscles & Burn Fat

This thing is no joke. I can feel the burn after just a few seconds. In fact, I can only do a few seconds at a time right now. This is one of the most powerful exercise products I have ever used.

Good padding and handle. Excellent rehab and exercise tool. Very good quality.

I wasn’t ready to fork out $150 for the Bodyblade Pro, and the Yes-4-all bar was the closest in weight to the Pro that I could find on Amazon. It doesn’t mean that the Yes bar offers the same level of challenge as the Pro (stiffness of the bar would be another important factor, for example). However, I was pleased to find that the Yes bar provided reasonable challenge for various exercises to strengthen and stabilize my shoulders. Moreover, you can get creative and use the bar in various ways to tone the arms and trunk muscles, and even the legs. I like that you can alter the level of challenge by changing the frequency of the oscillations. Sometimes I use the bar for some vigorous toning of muscles, and other times I use it for a slow burn (which may be useful for controlling blood sugar levels). Due to an over abundance of caution, I wear safety goggles when I work the Yes bar, in case I manage to break it during any frenzied shake session :-) But so far, after several months of use, the bar is holding up fine. The only minor con I find is that, for any exercise with this bar, you have to find the narrow band of trajectory for its oscillations for such to feel smooth; any deviation from such narrow band results in rough, uneven oscillations, as if the thing wants to jump out of your hand. Therefore some focus is required when using this bar for a smooth and effective workout.

Has sturdy construction. Easy to use. Good value for the price.

I purchased it to assist my balance in gym floor exercises. not terribly helpful for that so I bought something else for my intended purpose. I wish it was a bit LESS flexible so that I could put more weight on it. It seems to be built well. I'm planning on keeping it and attempting to work with it.

I really enjoy using these everyday. Quick twitch repetative motion really gets your muscles going. I have been using these everyday and can notice my endurance and strength improving. Two is mandatory. I bought one and then had to buy another one. I use two every time I use them. Get two.

Wife is happy

A little bit cheaper/flimsier than some of the other options, but the price is right and it gets the job done! This gadget is really good for getting a nice burn going in your shoulders. Really works the stabilizer muscles in a way that is very difficult otherwise. 4 stars.
