Not only for climbers

By amgeorg

Comments about Dyna-Flex Lighted Gyro Power Ball:

Our chiropractor suggested this product to my son, who is a violinist and was starting to develop wrist problems. Playing the violin, you develop the lower arm muscles in an unbalanced way. The Dyna-flex ball restores the balance. Just a few minutes a day for a few days made my son's wrist pain disappear. After that experience, I gave another ball to my other son, who is a computer scientist and was developing carpal tunnel from too much typing. He also had an immediate benefit and soon didn't have to use wrist braces anymore. After that, I gave gyro balls to many friends and relatives (including a drummer) who had carpal tunnel in the early stages. All had immediate benefits. This ball is not only for climbers!!! (and I should get a discount for buying so many of them!)

Comments about Dyna-Flex Lighted Gyro Power Ball:

I was skeptical of this little ball upon first glance. I've used the stereotypical squeeze toys for hand strength, and have found they do give a good pump after a while. I bought this on an impulse and can say I'm happy I did.

Not only does this gizmo work your forearm and hand strength, but depending on how you hold it you can also work you triceps, biceps, and shoulder muscles. Also you can vary the intensity but increasing or decreasing the speed.

I will say that it is difficult to start without the string at first. However, you can start it without the string but flicking the little rotor with your thumb. If you lost your sting or didn't recieve one like I did, you can use a small round shoe lace (think dress shoe) to start the rotor. It takes some practice to manipulate the rotor speed, but once you understand how to move your hand it's prety easy afterwards. It took me about 10mins of tinkering.

Overall it's a durable and relatively cheap training tool that can be used almost anywhere. One more note, it does produce a noticeable buzz when it's up at speed, but nothing obnoxious. Check out tha manufacture website for tutorials if you're having trouble.

Comments about Dyna-Flex Lighted Gyro Power Ball:

highly addictive... once you start you dont want to stop, good warm up for tougher activities... and also you cant really start it unless u have the string or the starter... that flicking technique doesn't really work or im not doing it right.also the rubber on the sides starts to chafe away at the fingers. (proly because I use it for about an hour each time)

Comments about Dyna-Flex Lighted Gyro Power Ball:

I am not a climber (I've always struggled doing just one pull-up) but I really enjoy using the Dyno-Flex. It really helps build muscle strength in your entire hand and lower arm - you can even feel it working on your upper arms and shoulder if you hold your arms out straight or above your head. Once you get it up to a high speed the sensation is very intense and exciting as you try to to maintain the gyroscopic forces. Everyone is correct that it does take a bit of practice to learn how to start and maintain the gyroscope. I never had much luck with the string. One thing you can do is roll it quickly on a smooth clean surface and then quickly hold your arm out and start rotating your wrist in a controlled steady manor, don't fight against the Dyno-Flex, rather let it guide your wrist around, keeping a steady rotation. If you keep this up it will pick up a lot of speed. As you get to higher and higher speeds your wrist will be moving in a much smaller circle as you try to contain the powerful gyroscopic forces.

The more you do it the easier it becomes to start it and control its speed. Also, as it strengthens your hand muscles you will eventually be able to start it with a few swipes from your thumb and no longer need the string or a clean flat surface. And you will have an awesome handshake!

Best Uses

Climbing Gym

Comments about Dyna-Flex Lighted Gyro Power Ball:

This product is very hard to "start". When I eventually got the string to start the Gyro after only four pulls the string got jamed inside the mechanism. Great idea but it should include a "starter" which is "sold separtely". Hopefully they will quit trying to sell add ons and just include the starter.

Good Luck

Best Uses

Typing

Comments about Dyna-Flex Lighted Gyro Power Ball:

This is by far the best hand, wrist, and forearm work out on the planet and there's the added bonus of being FUN! As you twist it faster and faster, the unit turns faster and thus puts more gyroscopic inertia in your hand forcing you to hold on tighter. You can use it while watching TV, movies, walking and its great fun at parties!

Comments about Dyna-Flex Lighted Gyro Power Ball:

This thing is great. As a drummer and bassist, my fingers and wrist get a hardcore workout nearly everyday. This is a great warm up/cool down tool. It also gives you sexy forearms after using it for a while. Also a great conversation starter with cute girls when I use the DynaFlex at the dog park.

Comments about Dyna-Flex Lighted Gyro Power Ball:

This is the most addictive and fun little toy that Ive had really. And it truly works wonders for hands, forearms and shoulders. I have noticed that my grip has improved quite a bit. I can tell that it has gotten better also because I have been able to use the device longer and longer without tiring. There is a speed meter you can get as well that shows your speed in RPMs that you achieve. my high score is 12,400RPMS!

Best Uses

Forearm conditioning

Comments about Dyna-Flex Lighted Gyro Power Ball:

First of all, this thing really works. I saw some reviews on another site saying it was a toy....no way! After you spin it for few minutes your forearms will be pumped; keep going and it will really start to burn. I have not had it long enough to comment on long term conditioning but it gives me that same pumped out feeling I get towards the end of a climb so I'm guessing it will really improve my conditioning. Make sure you try the upside down movement with your fingertips shown in the video. The nice part is that it does not cause any real stress on the connective tissue in your fingers like some of the gripper type devices that I have tried.

I would not get any of the sizes smaller than this one because it probably would not be strong enough. If you're a real beast (5.12+) the company website is now showing an even bigger one; but, this one generates sufficient force for me.

Its not as difficult to use as people say. It takes a few minutes to figure out- much less if you just watch the video that comes with the gyro. (I suggest you watch the video anyway...it made me laugh like heck).

You can also substantially vary the intensity of the workout by how fast you spin the gyro. This is a nice feature that is inherent in the device.

The string works fine to get it started. Just make sure you pull it straight out otherwise it can get wrapped around the spindle. This happened to me the first day but not since. You can work the string out with a paper clip.

Finally, this thing is not very rugged. I got one for my friend; he dropped in on a hard surface and the shell became dislocated. (note that while you are really spinning it, its easy to drop because it generates a lot of force). Luckily, we were able to take it apart an snap it back in place.
