Hand exercise balls are more commonly known as stress balls. They are available in a variety of sizes and resistances and can be purchased almost anywhere. Hand exercise balls can be filled with different materials including foam, air, beads, rubber, and gel. You can also get massage balls that have flexible spikes coming off of them, which are great for offering stimulating feedback and relaxing the fingers and hands.

Since these exercise balls are so small, they are very portable and can be used while you watch TV or read a book. Using a hand exercise ball is great for increasing your grip strength and improving range of motion.

When you are choosing a hand exercise ball, be sure to choose a ball that fits comfortably in your hand. You should start with a softer ball, as it will be easier to manipulate and slowly move up to the ones that have more resistance to them.
