Top Chi baoding balls are a hand exercise tool that have been used for centuries since the ancient times in China. It includes two solid steel balls which are rotated around in the palm of your hand. Depending on your dexterity level and agility, it can be easy or challenging. But that is why they are fun and healthy to use! Practicing daily with Top Chi baoding balls exercises the muscles in the hand and wrist. After you get the hang of the basics, more advanced techniques can be tried such as spinning the balls without them touching, rotating them in reverse, and even 3 or 4 balls per hand. Basic or advanced, all will build hand coordination and strength. Doctors have recommended the use of baoding balls as they help manage hand and wrist conditions. Top Chi's baoding balls include a convenient zipper carry pouch so you can easily carry them with you to exercise whenever your hands are idle. The pouch also has a disc you can place between the balls so they stay silent if rattled. Made from high quality stainless steel, you can't ask for a more durable set of balls. They are solid so they do not chime like traditional baoding balls. Use them anywhere without disturbing other people.
