This sport is for all ages and abilities and competitions are held at all levels. As with gymnastics grades competitions (NDP), trampolining starts with grade 6 and progresses to grade 1. Each set routine consists of ten skills all joined together, so that the landing from the first skill becomes the take off for the second skill and so on. Trampolinists reach their peak in their late 20's. Men's and Women's World Champions are nearly 30 years old.
