ok, i wanna know specifically, :- 1. The difference between cha cha and off beat cha cha 2. Are there any hip movement involved in these 3 dances I would appreciate thorough and complete answers as specific as possible. Additional information are appreciated. I'm not really interested in how's their every steps but I just wanna know the overall body movement involved in these dances. My gym is offerring these classes and I'm the kind that likes waltz and rock and roll but dislike rhumba. Basically I like dances that does not involve hip movement. So knowing about them would help me decide whether to take up these classes or not. If you have no idea, please don't attemp to answer. Thank you for your help.
