Convenient smart hand exercise ball

Try on this , addictive, multi-faceted device that is rapidly spreading across the world into the hands of the young and old alike! This is the Powerball Wrist & Arm Trainer!

It’s a baseball-sized handheld device that can be used in a fitness, sports, rehabilitation or fun manner making it fun, pleasurable and very addictive. With its gentle yet dynamic, non-impact nature and compact size it can be used anywhere and whenever you have time!

Features:

  • The Gyro Ball is a precision gyroscope. This gyroscope is composed of a rotor rotating at high speed (+15,000 revolutions / minute). The faster the rotor rotates, the greater the resistance. The muscles of the arm and the shoulder are therefore more and more solicited.

  • The Gyro Ball can generate the equivalent of 18Kg depending on the speed of rotation! It can also be used as a toy, a fitness object or even during a rehabilitation.

  • It has LEDs that change color according to the speed of rotation.

Specifications:

  • Category: Grip
  • Size: 70x70x55mm
  • Main material: polycarbonate, zinc alloy

How To Usse:

  • The operation is very simple but requires a little practice. Rewind the Gyro Ball in the direction of the arrows and let go when it gets hard. Take the Gyro Ball in the palm of your hand then make small circles to drive the rotor so that it rotates faster and faster.

Package Includes:

  • 1x Wrist Ball
  • 1x Wrist Strap
  • 1x Manual

    I have been using this everyday for a week now, with no issues, the only concern I do have is a bit of rattling inside but I am not sure if the ball is touching the plastic side or what, but these really work, you will feel your forearm burning and hands cramping, just keep doing this everyday and you will see some results.

    This is such a great product for helping with carpal tunnel syndrome. I do it for a couple of minutes on each side, and it started improving my symptoms in just a few days. It is a little difficult to get going, but once you get the hang of it, it gets easier.

    I've had incredibly weak forearms for as long as I can remember - probably about the same as my 8 year old niece. It's kept me from being able to do more than a few pull-ups at a time. I was skeptical that this little ball would actually give my forearms a workout. 30 seconds is what I can currently do before my forearm burns.

    This strength has really been crucial since just a month ago, I suffered a spinal cord injury. Had I not had this strength and endurance, I would have been sent to a rehabilitation home for recovery. I brought it to physical therapy, and they like them so much that they're going to purchase some for their clinic

    I got this ball because I was getting grip problems stemming from my work set up at home. It has kept my hands and forearms stronger than doing nothing.

    My wrist had been bothering me for some unknown reason. It was either trying to pick up a 20 lb baby too often and straining it or playing tennis 1X per a week. I didn't realize how important that muscle is to both activities until it started hurting. After 1-2 months working with this device, my wrist doesn't hurt doing either activity and is actually stronger than pre-injury baseline! Fantastic device once you get the hang of it.

    I love the work out that this compact item produces. I use it while watching tv or just walking around to get an easy workout in and I would highly recommend it to anybody working on their grip strength. The strings provided to start the rotation work great, and after continuous use, I'm able to start it without the strings, so it just adds to the usability anywhere.

    I didnt expect this thing to wreck my forearms like it did for the first week or so, it really works well. String start is nice, but not necessary. But, I wish they would make the top cap where the counter goes on the fancier ones a container with a lid to store the strings. That would make this even better.

    I love this! I dont have strong grip. I used this in different positions until I found the area that needed work. My grip has improved greatly!
