Everything,
If it's hiphop you're after, check out some of these people:
Shaun Evaristo <- best hiphop dancer in the world at the moment imho
Nick Bass
Marty Kudelka
Jun Quemado (sp?)
Shitkingz (a japanese group, also known as Shikken)
Patrick Cruz
U-Min
Youtube should find heaps of stuff on all of them. It really depends on what style of hiphop you want to pursue, you've got new school (most of those guys I've mentioned above fit in here), popping, locking, krumping, tutting, liquid, bucking and of course breaking/bboying (an entirely different moster on its own
)...the list goes on. They each have their own flavours, but lots of things cross over too.
Some things you can start with are:
Isolations - practice moving parts of your body independently to the rest...start with smaller parts like your hands or elbows, and move on to larger joints like your waist (remember even with your waist keep everything else locked in one spot). A more advanced version (and cooler looking) of this is isolating one part and moving everything else (eg, keep your hand at a certain height while the rest of your body raises or falls, keep your head in one spot while your body moves around it egyptian style). You will definitely need a mirror for this.
Hits - put some music on and tense all the muscles in your body as tight as you can. Hold for 16 counts. do this 4 times. Then continue with the following with a 4 count break in between:
4 x 8 counts
4 x 6 counts
4 x 4 counts
4 x 2 counts
4 x 1 count
4 x 1/2 count
this will give you the "ticking" attribute you see lots of hip hop dancers have. it will also make your moves look far crisper. The trick is, when you arent hitting is to remain deeply relaxed (IMA style!
).
