Boading Balls

You might have seen these balls on display in Chinese curio shops.   Made of metal or crystal, these Boading Balls are used for hand exercises and are reputed to confer health benefits by simulating the acupuncture meridians.

Beginners start with rotating the balls in their palms; it's a bit like bicycle riding, once one gets a knack of it, it's quite easy.  From there, the bar can be raised by incorporating more sophisticated techniques:

• Rotate the balls clockwise and counterclockwise;
• Exercise the other hand and later both hands;
• Rotate the balls smoothly without them touching;
• Use bigger diameter balls or more balls;
• Rotate the balls in three dimensions;
• Invert the hand, ie upside down;
• Rotate with the hand in a vertical position.
