Research breakdancing clubs in your area. The best way to learn breakdancing moves is by meeting with others and seeing first-hand how to perform the moves.
Look up breakdancing sites online. If there are no clubs or other breakdancers in your area, then watching the many breakdancing videos posted online is the best way to learn. Study the videos carefully and watch how experts perform breakdancing moves.
Buy a boom box (or another music system that runs off batteries), some tunes and a cheap rug. Set your rug down, start the music and practice some moves.
Start off by practicing popping and locking styles. This is where you dance, freeze in a position (locking), then pop back out of it. Try a knee spin, too. Drop down on one knee and pivot 180 degrees, alternating which knee is touching the ground.
Work up to more difficult moves such as the "Turtle." Lie flat on your belly, tuck your arms and elbows in and spin your body horizontally, using only the palms of your hands for support. From the "Turtle" work up to the "Windmill." Lying flat on your back, thrust your legs in the air and pivot 360 degrees on your shoulders to give the impression of a windmill.
Keep practicing moves until you have perfected them. After you have gained considerable experience, try out advanced moves such as the "Headspin." Some B-Boys wear a helmet to do this move, as it can be painful. Get into a headstand and use your hands to spin your body round. Once you have gained enough momentum you will be able to spin without using your hands.
Go out onto the streets and show off your new moves. Breakdancing came from the streets and this is where it is designed to be performed. Some B-Boys earn cash, in tips from people impressed by the show.
