I'm thinking about getting this DVD. I don't have a medicine ball - would I be able to substitute a free weight for the med ball exercises? Also, I'm really interested in the gliding section of this DVD. I'm assuming that the gliding section includes more leg work. I don't have the discs yet -- and I have read in some instances where people use sturdy paper plates. Do you think initially it would be okay to use the paper plates? Your suggestions/comments would be so very helpful. Thanks.
