When the rope is started, one hand holds the wrist ball with the opening part facing upwards, and the other hand inserts the plastic head of the rope into the small hole on the ball core; Turn the ball core forward with the thumb of the hand holding the ball and wind the rope in the central groove of the ball core. When the rope is still 7-8 cm, stop turning the ball core, remove the thumb to hold the ball tightly, quickly pull the rope outward to make the ball core rotate quickly, then turn the wrist downward and gradually exert force until you can feel the speed of the ball core increase.

Rotate your hands, hold the wrist ball with the opening part facing upwards, and put the thumb of the other hand on the opening side of the outer ball in the direction perpendicular to the central groove of the ball core. Move the thumb to the central groove forcibly to make the ball core rotate quickly, and then rotate the wrist downwards and exert force gradually. Turn with one hand, hold the wrist ball with the opening facing up, and move the ball core quickly with your thumb along the direction of the central groove of the ball core. After reaching a certain speed, immediately turn the opening downward, then turn the wrist and gradually exert force.

Wrist ball:

Wrist ball is the abbreviation of wrist fitness ball, also known as power ball, magic ball, gyro ball and super gyro. It was invented in Taiwan Province Province, China, which is common in Taiwan Province Province, and then spread to Europe and America, and promoted all over the world. Wristball is an artificial power device, which is purely mechanical, without batteries, any power supply and electromagnetic radiation. Wrist rotation drives the ball core to rotate at high speed, thus generating powerful force.

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. The powerful force generated by the high-speed rotation of the wrist ball is very helpful to exercise the strength and toughness of fingers, wrists and arms, which integrates sports, entertainment and fitness.
