Decide which style of street dance you would like to learn. Attempt to make friends with someone whose dancing you admire. Ask for resources or trade for one-on-one lessons.
Look up movies, documentaries and YouTube videos with dancers you would like to imitate. Watch movies like "Rize" for an authentic street dancing experience. Avoid movies like "Save the Last Dance," "Step Up," and other highly commercialized forms of hip hop dancing.
Take a hip hop dance class that specializes in "freestyle." Watch the teacher and students you admire most for technique and style. Sit in the back of the class and observe if you do not feel comfortable enough to participate the first day.
Download or purchase hardcore hip hop music. Use the soundtrack from "Rize."
Practice the moves you've learned in the privacy of your home. Focus first on chest isolation movements. Try controlling the arms, wrists and hands in the style of Popping and Locking. Experiment with footwork. Train different parts of the body separately and then try combining movements.
Record yourself. Compare your dancing to a dancer that you admire. Analyze the differences: What makes him better than you? Be honest with yourself and constantly critique your style. Make a commitment to learn one new movement a day but not until you perfect the ones you learned before.
Show up to hip hop dance productions or street dancing competitions. Observe the competitive attitude and confidence required to be a real street dancer. Participate when you feel comfortable.
