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.
There is a legend that, that the PowerBall was created under the direction of NASA 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 use correctly
After buying Powerball, many are wondering how, how to use it correctly. Of course, first the simulator must be started. There are two ways to do this: start with a lanyard or finger movement.
To make a lace start, you must adhere to several recommendations:
Find a small hole in the rotor and insert one of the ends of the lace into it.
With the help of your thumb, slowly begin to rotate the rotor and at the same time wind the cord around the rotor, pulling it on
It is very important to keep track of, so that the lace does not sag at this time, but tightly wound on the rotor. You need to stop winding the lace then, when they remain uncoiled approximately 5 cm
Now the ball lies in the hand with the counter to the palm, rotor up.
Taking the lace tightly with one hand, at the same time, it must be held second, so that he does not unwind. Then sharply and quickly you need to pull it with such force., to let the cord come out. If done right, then the rotor should start spinning at a speed 2000-3000 rpm.
Now the hand is flipping this way, the rotor "looked" at the floor and you can start making gradual movements with the brush. What matters is, that the movements should be made with the brush, not with the whole hand. Don't rush at first. Optimally will perform one revolution per second, it will help you feel the rotor better. If the movements are performed incorrectly, then the rotor will rattle.
Load, which the hand receives when using the simulator, directly depends on the rotor speed. In this case, you should be very careful., since gaining great speed, the simulator will try to escape from the hand.
Powerball Launch
To do this, you also need to adhere to several recommendations..
- Put Powerball in right hand, I follow, wherein, so that the lace hole is parallel to the hand line. In this case, it will be much more convenient and easier to make the starting movement with your finger..
- Left thumb perpendicular to the lace line, pad down.
- After that, it is necessary to lightly press on the ball and cut and spin the ball with a quick movement, while grabbing it with the right hand, in which he is.
Top 3 manufacturers of gyroscopic wrist bands
Powerball
Leader in gyroscopes introduces original Powerball machines with lifetime warranty. Among them are such patented types, like - Classic, Fusion and autostart.
Tournament
Chinese sports accessories brand also makes hand trainers, not inferior in efficiency to the original. Gyros reach 15000 revolutions, equipped with a counter, backlit and wrist strap for safe use.
Body Form
Another brand of gyro simulators, more budgetary, but striving to repeat the success of the originals. Trainers are highlighted, and the faster the rotation speed, the brighter the backlight.
What is a gyroscopic expander
Powerball - a revolutionary device for the restoration and strengthening of hands. All athletes need to increase strength for their chosen sport, gyro simulator can help in disciplines, requiring grip strength and arm muscles. When the Powerball is used for an extended period as part of an athlete's training program, it strengthens the muscles of the wrist, arms and shoulders.
Despite, that the gyroscopic expander is an excellent tool for athletes of all levels, it is also used in hand injury rehabilitation, including wrists. Increasingly, medical professionals are promoting the use of the Powerball for muscle and ligament injuries.
Muscle wasting is an unavoidable side effect of hand injury. Loss of muscle mass occurs during recovery, when the muscles don't work at all. Atrophy is especially common with fractures or sprains, if the hand is in a cast for a long time. Once the injury heals, you can start building muscle mass, practicing regular strength training. Rotating the Powerball for three minutes a day, it'll be enough.

How to start Powerball?
Spinning PowerBall is easy and simple, although it takes a little practice to hone the technique. We advise you to do it in this order.:
1. Insert one end of the lanyard into the connector on the rotor. Wrap the lace around the rotor along the groove, holding the lace with your fingers and turning the rotor with your thumb. Make sure, that the lace fits into the groove exactly, without sagging.
2. Leave the end of the lace approximately 10 centimeters unwound. Grasp the PowerBall tightly with your hand, which you are going to spin the ball (If you – right-handed – right, if you are left-handed – left, etc – powerball is very popular all over the universe), So, so that the counter on the top of the ball fits snugly against the inner surface of the palm. In this case, the rotor must face the ceiling..
3. With your other hand, grasp the loose end of the lace and pull on it, fast and strong (don't hold yourself back, the harder you pull, all the better). If you did everything right, the rotor will spin up to 2400-3000 rpm.
4. Immediately afterwards, flip your hand over immediately – the rotor should now point to the floor. Start rotating your hand (only brush!), holding the ball in slow circular motions. Again: you only need to rotate the hand in the wrist!
5. The main secret of simple ball spinning – start with slow movements after a strong pull on the lace. Start with leisurely wide diameter circles 15-20 centimeters, about one circle per second. Don't start with quick, short wrist movements, otherwise you won't be able to catch the rhythm, and it will be difficult to spin the ball correctly. If this happens, you will hear clicking inside the sphere – they arise, when the gyroscope tries unsuccessfully to pick up the torque.
6. As, how you slowly build up your rotation speed, you will feel increasing pressure on your wrist and arm. This pressure is proportional to gyroscopic forces., emerging inside the PowerBall. Reduce the diameter of rotation to 8-10 centimeters, increase the rotation speed to 3-6 laps per second. The shorter the circle, which your wrist describes, the faster the rotor will spin. The further – the harder!
To achieve high results (12 thousand revolutions per minute or more), need to practice. This is not difficult – rather, Powerball is hard to delay, until you hone your technique. After a while you will feel, that your hands are getting stronger. This will further improve results..
The main secret of going to 13 000 rev / m – radius of rotation approximately 1 cm., rotation must be continuous – hand and wrist look, as if they practically do not move, and the tendons are ready to explode with incredible force!
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.
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. Sure, 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.
Safety regulations
With all the safety, try to adhere to the following rules for handling powerball.
- If you have heart failure or any other heart condition, avoid exercising.
- You cannot touch a moving element.
- Try not to drop or throw the device, since heavy filling can damage the inner shell of the "apparatus".
- To train properly, avoid ball contamination, follow, so that no oily grease or liquid gets inside.
- Place the powerball firmly in the palm of your hand as you swing. If he slips out of hand and falls, it may not break, but the "knocking" sound, for sure, will appear.
