really there is no way, unless you are already a submission and boxing expert you absolutely need to have instructors and sparring partners, and no DVD's will not show you what you need. You can how ever start getting ready for MMA by getting your conditioning up and getting jacked. Get a good cardio program you will need to be able to run about 3 miles and then practicing your boxing and wrestling for at least an hour. If you show your parents that your committed they might change there mind.
