Hi there,
If you are about to begin the course you will be given a gym ball but will have to find your own method of pumping it up. A very cheap and small pump I found to be brilliant can be found at www.physique.co.uk for only £2.84 and you can also buy a plug remover for 66 pence. All very usefull if you find that your having to travel around with all the kit they give you.
Best wishes
