Squeezing a small ball is a very effective way to burn calories, work out your hands, strengthen your grip and relieve stress.

You can use a squeeze ball while you are watching TV, talking on the phone or anytime you are dormant. It is best to get a ball (a rubber ball or a tennis ball) that fits fully into the palm of your hand. Hold a squeeze ball in your right hand. Squeeze the ball as hard as you can, and then relax your hand. Repeat the exercise 10 times. Now use your left hand to exercise.

If you don't have a squeeze ball, just make and loosen a fist repetitively.
