i remember something about female teenage ice skaters working a lot of olympic lifts into their routines, all using light weights, done from the hanging postiton etc.....just to focus in on their explosivness because they were jumping about a lot and stuff
being pig ignorant about dancing i dunno what they would want, but i would have thought something like this is something you could gradually work up to....i saw an article on it on a website
(the program they followed), i'll have a search around for the link
plyometrics seem cool as well.....and focusing on different types of flexibilty, dynamic stretches, static stretches etc...
