Hi there! Aqua aerobics is really big in the UK, maybe visit some UK web sites?!? Im currently doing a course of aqua aerobics, and we do it in circuits, and there are about 7 "spots", covering arms, tums, legs - we spend 2 minutes at each spot, 1 minute on each leg, arm etc.
Anyway i dont know if this is much help!
