yup, there is plenty of ground work you can do with them in the meantime that will get them exercising. Teaching them to lunge etc is a great place to start and will teach them a lot of the things they need to know in the saddle. Also if they are a little nutty, this can give you a chance to assert your authority etc with them which is definitely going to be needed before you get in the saddle.
Good luck with them :)
