Wrist Exercise Ball - you can't resist the fun!
Gyroscopic Wrist Exercise Ball is an additively fun and powerful exercise tool that can build the strength of your upper body through a few minutes of workout every day.
This tennis ball sized Wrist Exercise Ball is a small engineering wonder: consists a freely revolving heavy gyroscopic rotor housed in a solid plastic shell, with a built-in digital speedometer/revolution counter, and self-powered LED lights.
Once setting the rotor in motion by using a cord, you can quickly build up its speed by moving the wrist in a circular motion. You may need some practices to get the act right, but once you get it work, you will feel like holding a hurrican in your palm! The gyro rotor is capable of spinning at astonishing speed: over 12000 rounds per minute! The faster the rotor spins, the bigger inertia force you will need to resist, and the more exercises work on your fingers, wrist, arm, shoulder and chest. And when your hands get stronger, you will be able to make it spin faster!
Apart from the digital counter, you don't need battery to use it. Even the LED light is powered by self generated electricity.
The ball weighs only 275 grams. However, at its maximum speed of about 12000 rpm, it will excert about 140 newtons (nearly 40lb) of gyroscopic inertia force to your hand! That's some serious exercise human body can sustain. And you need to work very hard to achieve that kind of speed. As you can see from the photo, I can only do 9228 rpm with all my effort.
This kind of gyro execising devices has been around since the 1970s. But there is a phenomenal resurge of players of this magical ball in recent years because reserchers have discovered that a wide range of users can benefit from playing the gyro ball, ranging from fitness buffs, sports pros, rehabilitation patients, and even musicians.
Fitness
The Wrist Exercise Ball can be used as fitness equipment for you to exercise your fingers, wrists, hands, forearms, biceps, triceps, ligament, shoulders and chest! You can decide what resistance you want to workout with, at a range from 0 - 40 lb. If you just want to tone and shape the arms and shoulders but not muscle growth, you can achieve excellent results from using it at between 6000-8000rpm for around 10 minutes each day.
However if you want to develop a powerful arm, you need to ramp up to above 12,000rpm as the resistance force climbs in proportion to the speed of the internal rotor and at its maximum speed the simulation to your muscle growth can be extrodinary.
The other unique advantage of the Wrist ExerciseBall is that, unlike a traditional fitness equipment that works on one specific muscle group each time, it can work on most of the muscles in the arm in a single session!
Sports
Because the Wrist Exercise Ball can effectively develop the power of your upper body, it will benefit your capability of playing all swing based sports, such as tennis, badminton, table tennis, squash, bowling and golf. For other sports involving hands, wrists, forearms and shoulders, such as rock climbing, mountain biking, rowing, boxing, you will find the Wrist Exercise Ball will give you extra resilience, endurance and rigors for you to excel.
Even musicians may benefit from the exercise as they need strong hands to play music.

The Wrist Exercise Ball has been used to replace traditional exercise routines for better rehabilitation results of damaged muscles. While traditionally fixed weight is used for rehabilitation exercise, which run the risk of damage to existing inflamed areas, you can easily control your workout strength with the Wrist Exercise Ball to avoid the problem.
