Hip hop dancing relies a lot on the contrast between loose, flowing moves and quick, jerky ones. Generally, the hips are kept loose while the arms and hands perform sudden, dramatic movements, though quick hip moves are not uncommon either. The first step to making your dancing more hip hop-like is to embrace this contrast. Popping and locking are two dance styles that provide a foundation for a lot of hip hop dance technique. Learning the basics of both will allow you to quickly look more like Beyonce while dancing.  Popping: This is a bouncy style of dancing that requires the isolation of body parts, moving them in succession, to the beat. To perform popping, imagine a wave moving through your body, making your body parts move one after another. Locking: The basic concept of locking is to move quickly and then freeze, and then continue moving at the same speed as before. This can be applied to both the whole body or to one body part at a time. Usually, locking involves jerky arm movements and a looser hip area, which moves to the beat. Once you understand the basics of popping and locking, you can learn a few basic hip hop moves that will get you started. These moves are the kind of things they'll teach you at almost any beginner's hip hop dancing class.  Hip step: Start in the standard position with your feet shoulder length apart and knees slightly bent. Kick one foot out in front of you, then swing it to the outside of your other foot, crossing your legs. Then uncross your legs by moving your other foot back into standard position. Repeat in the other direction. Slide and step: From the standard position, move your feet closer together. Then step far to the side with one foot. Slide the other foot towards the first foot and then step it back into place next to the first foot. Then repeat in the other direction. Arm cross: Lean your torso forward a bit. Spread your arms in either direction, outwards but still pointing toward the floor. Then swing your arms both in and cross them in front of you. Move your hips back and forth to the beat as you do this.

Summary:
Utilize both relaxed and jerky movements. Introduce popping and locking into your dancing. Master some of the basic moves of hip hop dancing.
