Follow the links to see the animation. Practice each step until you are confident before moving to the next step.
Step 1. Start with one ball that goes up in the middle and down on the side to the other hand. Try to keep all throws equally high.
Step 2. Now use two balls. Just before the first one lands, throw the other ball back below the first one. Both throws should be like in Step 1.
Step 3. Learn the same as in Step 2, but now starting with the other hand.
Step 4. For learning how to start and stop, you need to have two balls in the same hand. Hold one ball with your thumb, index, and middle fingers, and the other ball in your palm. Throw the ball in your fingers first and immediately after catching it, move it to your three fingers. Catch the second ball in your palm.
Step 5. With three balls, do three throws starting from the hand holding two balls. First learn one side, then start with the other hand, just like Steps 2 and 3. You could also try four throws. You will learn faster by doing short controlled runs rather than trying and failing to juggle continuously in Step 6.
Step 6. Congratulations, now you know how to juggle! This pattern is called the 3-ball cascade.
