Wrist power ball is the fastest artificial power device in the world. It is purely mechanical, without batteries and any power supply, and without electromagnetic radiation. The rotation of the wrist drives the ball core to rotate at high speed, thus generating powerful power.
Through manual control, the rhythm and speed of ball core rotation can be adjusted at will. The faster the speed, the greater the strength, which can be equivalent to 50 kinds of dumbbells with different weights. There is about 14kg force at 8000 rpm, and about 22kg force at 10000 rpm. The world record has exceeded 20,000 revolutions per minute.
Because of the powerful power generated by its high-speed rotation, it is very helpful to exercise the strength and toughness of fingers, wrists and arms. It integrates sports, entertainment and fitness, and is increasingly favored and loved by people all over the world.
Wrist force ball uses gyroscope and conservation principle of angular momentum, constantly rotates under the action of inertia law and angular momentum, and generates powerful force, which makes wrist and arm in autonomous motion.
And wrist ball can enhance the strength of fingers, wrists and arms (grip strength, wrist strength and arm strength) and enhance the toughness of fingers, wrists and arms.
The rotation of left and right hands can improve the balance of left and right brains, make fingers, wrists and arms more flexible, and at the same time promote blood circulation, relax muscles and tendons, relieve discomfort, eliminate fatigue and improve health.
