Strengthen your arms in a new fun way with the innovative Powerball. It's only as big as a tennis ball and fits great in your hand. You do not have to visit expensive gyms and work up a sweat lifting dumbbells. Due to the gyroscope system and high-speed rotations of up to 18,000 RPM, you get a heavy counterweight in your hand. Practice comfortably on the way to work, or while watching TV or reading the newspaper.
This device effectively use the principle of a gyroscope. Inside, you will find a sphere rotating around an axis, whose ends are connected to a steel ring and as a result of circular movements, it will spin. With high speed, the ball will remain in equilibrium and exert a force against your hand. When the ball is spinning at its fastest, the force will be equal to a weight of over 16kg.
The Powerball provides a good workout. It is perfect for customers who work in industries where they mainly use their hands (for example, computer-based). Improve any problems within a few weeks of use. In addition, you choose which part you want to train and at what intensity according to your own specific condition.
The Powerball has a built-in speedometer. Compete with colleagues at work, with friends or family, to find out which of you has the most powerful hand. The computer offers 6 functions, including current speed, average speed and maximum achieved speed. It is very important to maintain a particular speed for at least 20-30 sec for maximum effect.
You can increase muscle mass on your entire arm, wrists, forearms, biceps, triceps and even pectoral muscles, all with one magical ball. There are no catches; the Powerball has been purchased by millions of satisfied customers. This small ball will do the same work as up to 50 kinds of dumbbells, which wouldn't be anywhere near as easy to carry around with you as the Powerball.
