Advantages and disadvantages
so, from all of the above, we can conclude, that the Powerball hand trainer has both advantages, and disadvantages.
The advantages can be safely attributed:
- mobility;
- efficiency;
- helps to recover from hand injuries;
- helps to strengthen the hand and wrist;
- works without batteries;
- strength.
The disadvantages include its cost and then, that at first, after training with Powerball, your hand may ache.
There is a legend that, that the PowerBall was created under the direction of NASA in order to, so that astronauts train in a weightless state. In space, there is no way to use gravity, and therefore scientists have created training aids., replacing gravity with centrifugal force. And finally, together with kinestherapists, they invented the PowerBall gyroscopic trainer..
How to choose
There are many Powerball models today. How to choose a hand trainer? Worth emphasizing, that all models can be divided into non-luminous and luminous. And also models with additional functions.
Inside the luminous exercise equipment, or as they are also called Powerball Neon, there are six LEDs and a device, which makes them glow when the simulator is running. Batteries are not required for these models, because Powerball works from the rotation of the rotor. Models can be seen in three colors: green, blue and red.
Metal Powerball
In addition, you can see glowing exercise equipment with a built-in counter., thanks to which you can find out at what speed it rotates.
Powerball 250hz, not equipped with LEDs, are distinguished by their rotor balancing, which is ideal. Since during production the rotor is first centered, and then LEDs are built in, then its balancing may go astray. Of course, it's almost imperceptible, but a well-balanced rotor can perform 150000 rpm. You can see Powerball 250hz in blue and orange. You can also see such models with a built-in counter..
Powerball prices range from 900 rubles to 2500 rubles.
Top 3 manufacturers of gyroscopic wrist bands
