Dobry den mate v popisku chybu, purple je fialova ne ruzova :)
Boost your arm workouts in a new and entertaining way with this innovative Powerball. Its tennis ball size fits in the palm of your hand. There is no need for expensive gyms and sweaty lifting sessions! Thanks to a sophisticated gyroscope system and high spin speed of up to 15,000 rpm, you can exercise anywhere. Spin it while watching TV, reading the newspaper or traveling to work. This special edition is designed for all purple lovers.
The basic principle is the gyroscope function. Inside there is a sphere rotating around an axis. Due to the high speed, the ball tends to remain in the equilibrium position and thus acts against your hand. During a rapid spin, the force against you can equal a weight of 18kg.
You can increase the muscle mass of your wrists, forearms, biceps, triceps and even pecks with this magical ball. Powerballs have already satisfied millions of people just like you.
You can buy a speedometer to compete with your colleagues at work, friends or family. The speedometer includes 6 functions, including current, average and maximum speeds. It is important, however, to spin for at least 20-30 seconds for accurate measurements.
Powerballs are perfect for customers who work in industries where their hands are active (for example, computer-based industries). Reduce your wrist pain after just a few weeks of use. You get to choose which part you want to work and for how long according to your own individual condition.
