The basic skills referred to are kneebend, posture, extension and flexibility but these are given in the form of exercises such as holding the extensions in big held edges. holding and extending positions in back crossovers while working on posture at the same time. Flexibility involved trying advanced types of spirals (Y spiral for example). Exercises involving combinations of steps including mohawks with extensions, runs, steps to forward etc and some work on spins.
I'm not sure what level the lowest level skaters were but if you are not comfortable with holding extended edges and crossovers forwards and backwards and mohawks etc you would not get a lot out of it. If you are comfortable with those then it is a great way to really practice those things (extension posture and kneebend in particular) which can really make you look like a 'skater' rather than an 'adult skater'
Note that this is not a camp to learn any of the elements of skate UK but to do intensive work on improving skills skaters already have.
Intermediate is for those who attended the July camp or who will do the September basic skills camp first.
