Powerball is a hand and forearm trainer based on a gyroscope. It is actively acquired not only for sports purposes, but also for the prevention of carpal tunnel syndrome, which has become a real epidemic of the 21st century due to the rampant development of computers and mobile devices. This gyroscopic trainer will tone your arm muscles, teach them proper relaxation, give strength and excellent coordination.

Powerball Benefits:

• ideal biomechanics of exercises;
• treatment and prevention of carpal tunnel syndrome;
• no risk of injury;
• affordable price for any Powerball model;
• durability;
• compactness - the hand trainer fits easily into your pocket.

powerball features

The simulator has a spherical shape, the body is made of plastic or rubberized material, partially covering the rotary gyroscope. The initial movement of the rotor is set using a lace or, if desired, in another way. The more the rotor rotates, the more difficult it is to hold the simulator in your hand.

Basic movements with a gyro trainer

There are three main movements in which the forearms are involved to a greater extent. All of them are shown in these illustrations:

It is not difficult to see that some of these movements are the main ones for certain hand trainers. For example, flexion and extension of the fingers is more related to classic expanders. According to biomechanics, this is quite effective simulator, but he is able to load the forearms with only a few basic movements. Powerball combines all possible types of load that allow you to comprehensively influence the development and condition of the forearms. This is kind of the only "basic" hand trainer.

The load will always depend only on your current condition of the forearms. The maximum rotation speed is limited by the strength of the forearms. This is how the manufacturer was able to completely eliminate the possible risk of injury. Now it is the safest hand trainer.

Which model to choose?

The online store has a huge collection of gyro trainers, you can choose and buy the Powerball to your liking - the classic model with a rubber band or tape, rubberized versions and other solutions:

• Classic. In most cases, a special rubber strip is applied to the case for a more durable and comfortable hold. There is a display with the calculation of the speed of revolutions, duration and total record. Made of plastic or metal;
• With special tape. Quite often, athletes complain about the fear of dropping the projectile. Naturally, this leads to a decrease in the number of revolutions of the rotor. To get rid of such a phobia, the manufacturer produces special models with a rope that is attached to the wrist. Thus, even with an accidental relaxation of the arm, the simulator will not fall;
• Special fortified. The case has a denser rubber coating;
• Metal. Have a spectacular appearance and increased weight;
• With backlight. Allows you to train in the dark. Neon lights and high rotation speeds are another way to spruce up your workouts and avoid monotony.

Powerball is gyro simulator(carpal expander), designed to train the hands and forearms. It involves the use that the user makes when working with the simulator in order to create a constant load on the muscle groups of the hands and arms.

The question may arise: what is powerball for? This modern expander can be used by almost everyone, both for those who wish, and as a sports simulator for those who are seriously involved in sports. That is, you can just have fun with powerball, or you can, by exercising regularly, maintain the tone of the hands and muscles of the hands. Of course, the powerball is not designed to pump up huge muscles, but using it will make your hands more tenacious and enduring.

That's it for this that a carpal expander is needed for everyone who is associated with work (occupations) that create constant loads on various muscles hands (fingers, hands, forearms). And many people can be attributed to such categories: musicians, climbers, cyclists, tennis players and many others. others. By exercising regularly with powerball, you will soon feel that your fingers, hands and forearms obey you better, do not get tired, do not get numb, etc. In addition, powerball exercises have become fashionable and continue to gain popularity among modern business people.

You can watch an excellent educational program on powerballs in this video.

But what about the athletes? What pumps the carpal expander? Well, firstly, it not only pumps muscles, but is also recommended for all athletes (regardless of the sport) for classes to restore the mobility of the hands after injuries or injuries. It is also indispensable for preventive purposes to prevent pain in the hands and wrists during overexertion.

Powerball pumps almost every muscle in your arm

So what muscles does the powerball carpal expander pump? The answer to this question lies in it. It looks like a pretty simple trainer. However, behind such a rustic appearance, a gyroscope is hidden, the principle of which is that if it is activated, then in this state it will counteract any external influence on it. So than faster athlete spins the powerball, the more resistance it receives from it. That is, his hands, forearms and other muscle groups of the hands receive an increased load.

The powerball simulator is quite affordable (price range - from 900 to 2300 rubles, depending on the configuration). This modern carpal expander is perfect for relaxation, sports, entertainment, competition, and also as a great gift to your friends.

The gyroscopic arm trainer is developed on the basis of a gyroscope, a device that was previously widely used to determine spatial directions. Currently, the device is used mainly by people prone to developing carpal tunnel syndrome. The advanced stage of the syndrome needs serious inpatient treatment. To avoid such problems, it is recommended to engage in the prevention of the development of wrist joints. And for this, as well as possible, a gyroscopic simulator is suitable.

Design

Externally, gyroscopic simulators have the outlines of a small spherical object. The base of the case, in most cases, is made of durable plastic in different colors and levels of transparency. At the same time, there is a whole mass of metal models of gyroscopic simulators. However, such options are somewhat overpriced and are used mainly by advanced athletes.

The gyroscopic simulator may contain an electronic revolution counter in the upper part. Some lower cost models have only seat for similar accessories, which can be purchased separately, if necessary.

At the bottom of the simulator there is an open area through which you can see the operation of the rotor. It starts with a special thread. The case of such devices is often covered with elastic rubber pads, which contributes to the confident holding of the simulator in the hand.

Separately, we should mention the illumination of gyroscopic simulators for training. For example, the torneo gyroscopic simulator, like a whole host of other popular models, has dynamic illumination, where the brightness of the glow and its hue change based on the intensity of hand movements and the speed of the rotor.

Principle of operation

As noted above, a gyroscopic simulator operates based on a rapidly rotating rotor in the middle of a plastic sphere. The training is based on the implementation of circular, with the hand, which adds additional speed to the spinning rotor. The rotation of the simulator with the activated rotor leads to the action of oppositely directed forces on the hand, which requires a firm hold of the device in the hand.

The launch of the rotor together with the tilt of the simulator to the sides causes the axes of the device to move along special grooves - upper and lower. The friction force between the axles and the groove structure can slow down or speed up the rotation of the internal gyroscope. Maximum acceleration becomes most noticeable when the rotor axes acquire the smoothest sliding along the grooves.

The presence of friction plays a decisive role in training with the help of a gyroscopic simulator. Therefore, in order to achieve a noticeable effect, it is not recommended to lubricate the mechanisms of such devices.

How useful is a gyroscopic simulator?

The behavior of a gyroscopic simulator with the rotor running is somewhat reminiscent of the action of a spinning top or a yo-yo toy. However, unlike these devices, the “gyroscope” makes it possible to enjoy the well-coordinated work of the internal mechanism, develop joint flexibility, train muscles and hands, achieve high results, and set your own records.

It is recommended to purchase a gyroscopic simulator (250 Hz), or devices of any other power, for people whose daily activities are associated with the need to perform the same type of hand movements in a sitting position. The efforts that will have to be made to exercise on a gyroscopic simulator will activate not only the joints and muscles of the hands, but also make the forearms and the entire shoulder girdle work.

Gyroscopic simulator - how to use?

The operation of gyroscopic simulators is possible in the absence of any batteries. To activate the rotor of the device, it is usually enough to start it with a special cord with active rotational movements with the hand.

It is possible to increase the complexity of training on the simulator by performing rotational wrist movements in the opposite direction to the rotor revolutions. This approach leads to the appearance of resistance between multidirectional forces, which will force the muscles of the hand to overcome the additional load. In this case, the impact of the simulator falls not only on the wrist area, but also on the shoulder girdle area.

Not required to use the trainer. special training or a certain level physical development. The device is suitable for users of all ages, including children and older people.

on a gyroscope

1. Triceps training requires the tightest grip of the body of the simulator with your fingers. AT starting position the hand is in a relaxed state, lowered down. The essence of the exercise is to perform rotational movements of the forearm in the frontal direction in a clockwise direction with a gradual increase in the speed of revolutions.
2. consist in raising and lowering the arm bent at the elbow joint with the simulator clamped in the hand. For also smooth, rhythmic rotational movements brush. With the most active movements, the entire upper arm is additionally trained.
3. Workout pectoral muscles involves holding the simulator on an arm extended to the side. It is necessary to perform rotational movements with the brush so actively that loads are felt on the entire arm and chest muscles, right up to the neck itself.
4. To train your fingers, it is enough to make rotations, firmly holding the simulator with your hand. The load on the fingers can be adjusted by moving the simulator closer to their ends or to the palm. To achieve high results and increase the effectiveness of training, it is recommended to change the sides of rotation.

Who can be pleased with a gyroscopic simulator?

The gyroscopic simulator can become effective tool overcoming the syndrome of tightness of the carpal tunnel, removing muscle fatigue, as well as the development of joints and muscles of the wrist for the following categories of users:

• experienced office workers;
• people whose activities are associated with the need for a long stay in a sedentary, sitting position;
• users who have to spend most of the day in front of a computer;
• older people who suffer from a lack of activity;
• schoolchildren and students who need to develop their fingers or overcome chronic tightness of the wrist joint.

So, you have purchased a carpal powerball trainer. Now the question is before you. And that means you have to know how to launch the powerball and how to spin the powerball.

Here you have a powerball in your hands . It can be launched in two ways:

Launching a powerball with a lanyard.

The launch of this simulator, in general, is not difficult to produce. But, of course, you need to practice a little with the powerball first. Heed some advice:

• We insert one of the ends of the lace into a small hole in the rotor. We begin to smoothly rotate the rotor with thumb hands while pulling the cord and winding it around the rotor. At the same time, it is important that the cord wraps tightly around the rotor and does not sag.
• We stop winding when about 5 cm of lace remain unwound. We take the ball in the hand with the counter towards the palm (rotor, respectively, outward).
• Firmly grasping the lace with one hand (while holding it thumb with the other hand so that the lace does not unwind), quickly and sharply pull it with such a calculated force that the lace comes out completely. If all this is done correctly, then the rotor should start spinning at a speed of about 2000 - 3000 rpm.
• Now you need to quickly turn your hand over so that the rotor is facing the floor and start gradual movements with your hand. It is very important here that the movements must be made with the brush, and not with the whole hand. At first, it is advisable not to rush and make no more than one revolution per second. This is necessary in order for you to feel the rotor. With the wrong moves, your powerball will start to rattle.
• In order for the start of powerball to be easy, there is one little “secret”. It consists in the fact that you need to start the rotation of the simulator slowly enough. That is, by giving the rotor initial speed using a cord, you begin to slowly spin the simulator only with your hand at a speed of 1 rpm. It is not worth turning fast, since you most likely will not succeed. You must learn to feel the rotor and make synchronized circular motions.
• In the future, the faster the speed of spinning the rotor, the more load your hand will receive. But you need to be careful and hold the powerball tightly: when high speed the ball will try to escape from the hands.

This video shows the described method. See how the pros do it:

Zpowerball launch without lanyard

We note first that this method of starting the simulator requires good training and does not work out for everyone right away.

Procedure: holding the powerball in one hand, you need to start spinning the rotor with the second hand (palm or thumb). If everything goes right, then this rotor speed is just enough to continue rotation only with the help of circular motions brushes.

And one more video from the pros about the launch of the powerball:

Powerball is an exciting simulator, which perceptibly resists your influence on it. It is suitable for and. Powerball is contagious - give it a few minutes and you won't be able to put it down. Powerball is an amazing item that will impress your colleagues and friends. In a few weeks, Powerball will increase the endurance and tenacity of the hands at times.

Powerball works using the gyroscopic effect that occurs when its rotor rotates. We have written a short explanation, as applied to this simulator.

You can buy Powerball from us in a wide price range. Models differ in the material from which they are made, as well as the presence of a counter, backlight, the possibility of autorun and protection against falls.

On our website you can buy Powerball with delivery in Yekaterinburg and Russia.

In addition, we deliver Powerball throughout Russia cash on delivery.

Office fun with Powerball

Powerball is great for fun. This small area, despite its apparent simplicity, is instantly addictive. In any company, club or just a crowded place, it will attract the eyes of all the people around you, especially if you have a Neon model with backlight.

Also, Powerball can stop life in an ordinary office for an hour - show it to your colleagues and be sure that no one will return to work without trying it in action. And don't be surprised to see the same Powerball from your colleagues in a week. Powerball is a very attractive device.

In addition, the hyped Powerball Neon Blue is very similar to the flashing beacon of government vehicles. By holding it under the windshield of your car, you will certainly gain honor and respect on the roads. At the very least, resourcefulness. :-)

Hand and forearm trainer Powerball

Powerball is a unique sports simulator. It replaces the expander, dumbbells and boring workouts. Spinning its rotor at least up to 11,000 rpm, you will get a load on your arm of more than 12 kilograms. What is important, this load is evenly distributed between the hand, forearm, biceps, triceps and shoulder - depending on how you use your Powerball. If you spin it with your arm down, then the load falls on the hand and forearm, which allows you to use the Powerball as a hand trainer. If you hold the hand with the rotating Powerball horizontally, then most of the load is on the shoulder. If you bend your arm and rotate the Powerball over your shoulder, then a significant part of the load will fall on the biceps and triceps.

Most importantly, training with the Powerball is not emotionally exhausting - the Powerball comes to life in your hands and you will most likely want to spin it more and more.

Interestingly, all models with the prefix Pro in the title are equipped with a rev counter, which allows you to record your achievements and participate in our table of records.

The maximum load exerted by your Powerball on your hand can be up to 20 kilograms, with a rotor speed of more than 15,000 rpm.

Gift with benefit

You probably already understood that getting a Powerball as a gift is nice. Not only pleasant, but also useful. Not only useful, but also exciting. Everyone knows that there are only two types of gifts: interesting for everyone and personal. A personal gift is unlikely to be shown to anyone else, so we will not consider this case. Powerball is a completely different story. It was created to attract attention, everyone will ask where they can get one and ask to try it - you need to be ready for this. This small wayward sphere is a subject of attention and slight envy for those who do not yet have it. Those who already have it will look at the owner with a slight smile of connoisseurs and ask: “Well, how much have you already wound up? 10000? ha, and I'm already spinning under 13000!

Why are we telling all this? Moreover, Powerball is a wonderful gift that will last a very long time and bring a lot of benefits and joy to the owner.

Powerball for photographers

If you are a professional photographer, and reportage photography is your specialty, then Powerball can help here too. Imagine: you need to lift the camera and lens, which together can weigh about 3 kilograms, capture the frame and press the shutter, keeping the camera on the weight! A beautiful shot can be pretty spoiled by hand tremors.

The Powerball will help you strengthen your shoulder, forearm and hand so you can easily capture great handheld shots without the need for a tripod and flash.

Powerball for climbers

Climbers know for sure that finger, hand and forearm endurance is the most important requirement for this sport. There are two ways to achieve this endurance: either by constantly training, or, which is more likely for city dwellers, by exercising with the Powerball simulator. Try Powerball at work: 12-15 kilograms escaping from your hand are worthy of respect as a training tool. Stop the Powerball hand trainer and you'll be surprised how little it actually weighs - it weighs less than 300 grams when stopped. Train everywhere: at work, at home and even on the go.

Hand pain

The brush is very main part arms, which is subjected to a heavy daily load associated with the use of a computer, pen, drawing or musical instruments. If after a few hours of working at the computer you feel that your hands go numb and your hands start to hurt, your fingers start to tremble, or you feel pain in your wrists, then this is the first symptom that you have "carpal tunnel syndrome", or, more scientifically speaking, carpal tunnel syndrome". It is related to the structure hands. The fact is that the hands can hardly endure monotonous short movements for several hours or the whole working day, and such activity causes compression of the nerve in the anatomical canal.

To keep the hand in good shape and avoid various diseases associated with monotonous activities, as well as pain in the hands, doctors recommend doing hand exercises and taking breaks from work at least once every two hours of work. And in order to do hand exercises and avoid nerve clamps, it is best to do a simple exercise with Powerball.

Rotate the hand trainer Powerball for two or three minutes so that the number of revolutions of its rotor does not exceed 7-8 thousand revolutions per minute (the second mode of operation of the electronic counter), and you can easily avoid heavy hand diseases related to your professional activities.

Besides, Powerball Great for repairing ligaments and tendons after physical hand injuries such as fractures and dislocations. For recovery, we recommend rotating the Powerball for several minutes so that its rotor rotates at a speed of no more than 5-6 thousand revolutions per minute.

Gyroscope and the physics of its work

powerball- gyro simulator, which allows you to train the hand and forearm of the hand. The Powerball can be launched either with a special thread that is wound around the inner rotor and pulled out sharply, or with a quick sliding movement of the finger. When the inner rotor spins up to 2-3 thousand revolutions, the person holding it in his hand can accelerate the rotor to tremendous speed by making circular movements with the brush. The professional version of the device comes with an electronic revolution counter that allows you to set records for the number of rotor revolutions (RPM) per minute. The current world record is 16218 rpm. In addition, there are luminous models Powerball, which has several diodes and a dynamo that generates electricity to run them.

The principle of operation of the device is very simple. In order to understand it, you need a minimal understanding of the principles of the gyroscope. If applied to gyroscope constant external force, then it will begin to rotate around some axis that does not coincide in direction with the main axis of the rotating rotor., i.e. precess. In this case, the rotation does not occur in accordance with the direction of the external force. The precession value is proportional to the value operating force. In the event of termination of external influence, the precession ends instantly, but the rotor continues to rotate.

Axis gyroscope in the Powerball is fixed inside the rotor and can move along a small groove inside a plastic sphere that covers almost the entire gyroscope inside itself, except for a small open part through which you can run gyroscope. Once the rotor is spun, tilting the device will cause one end of the axle to move along the top side of the groove and the other end down the bottom. When the axis of the spinning rotor comes into contact with the top and bottom surface of the groove, it will cause precession and the rotor axis will begin to circle along it. The frictional force between the axis and the groove surface can either speed up or slow down the rotation of the gyroscope. The greatest acceleration is achieved when the rotor axis begins to “slide” along the groove surface as smoothly as possible. Since the frictional force is very important for this effect, the device must not be lubricated. Achieve maximum acceleration gyroscope it is possible when it is firmly held and the rotation is constantly supported by the movement of the brush.

How to clear Powerball?

To clean the ball, you need to get to the place where there is a vise - this is a necessary condition in order not to damage your Powerball. Of course, you can disassemble the ball without that, but the vise is the best option. In addition, you will need a Phillips screwdriver with a tip diameter of no more than 2mm and a regular screwdriver of any size. Next, you need to do the following:

1. Remove rubber band with Powerball inscription.
2. Using a Phillips screwdriver, unscrew the two small screws hidden on the surface in the place that the tape covered.
3. Put on the rubber band again.
4. Place the Powerball in a vise so that the teeth are opposite where you removed the screws from.
5. Turn the vise handle one or two turns until you hear a click.
6. Remove the ball from the vise. If you don't have a vice, you can put the ball on the table so that rubber ring went vertically from the surface of the table, then apply a slight blow with the palm of your hand, or with a book or something else. Do not be afraid to damage the ball - it is made of strong plastic. Of course, putting a table on top of it or hitting it with a door is also not worth it, so do everything within reason. The ball should make a slight click.
7. Remove the rubber band.
8. Using a regular screwdriver, separate the two hemispheres of the Powerball at the point where they began to diverge.
9. Remove the rotor, clean its surface and the surface of the sphere. It is best to do this with a dry, clean cloth, as an ordinary napkin leaves paper particles inside the sphere, and any grease or moisture can kill your Powerball forever.
10. Install the rotor in one of the hemispheres.
11. Snap the Powerball so that the arms of one hemisphere fall into the sockets of the other.
12. Screw in the screws.
13. Wear a rubber band.

How does the Pro model counter work?

Turns counting mode. This is the mode in which the number of revolutions of the rotor is calculated, from the moment of start to the moment of stop. Turnovers are measured in hundreds. If the result on the screen is 83, then the rotor has made 8300 revolutions.

Speed ​​counting mode this moment . The counter in this mode shows the speed of rotation of the rotor at the moment. Measured in revolutions per minute.

Record setting mode. In this mode, the highest achieved result is recorded. The result is stored in memory until you press CLR or until you break the record. The counter will automatically fix new record if you beat the previous one.
In this mode, the counter shows the maximum speed since the start. If the result is not better already set record, then the counter will show it only until it stops completely, after which it will return to normal mode.

Force Index Mode. Press FCN to the symbol. This is a mode in which the number of revolutions is counted for 30, 60, 90 seconds from the start. Once launched, a countdown will begin on the screen. For a record, you need to turn the rotor by top speed within 30, 60 or 90 seconds.

Legend

There is a legend that the gyroscopic hand trainer was invented in the USA under the leadership of NASA to train astronauts in a state of weightlessness. Since there is no possibility of using weights in space, scientists designed aids for training, using centrifugal force instead of weights. Together with kinestherapists, they eventually created POWERBALL, a gyroscopic simulator.
