The Lock or 'Locking'

Locking is doing some fast moves with the entire body, then freezing in one position. The best way to describe the movement of locking would be this: You know those little-figured toys that are like inside-out puppets on small plastic circular platforms or pedestals, and if you press the bottom of the platform the figure collapses real fast, then when you let your finger up it goes back into shape? Well that's what locking looks like.

The Pop

The Pop is a popping movement of different parts of your body, achieved by tensing the muscles. It is very rhythmic, and matches the popping rhythmic style of the music. You can Pop your elbow by sticking it out, or your shoulder by hunching it. The rest of your body remains still.
