I don't why anyone else said fitness training and sparring everyday.
In fact, my approach was totally different. I would go through everything (strikes, locks, submissions, falling, weapons, weapons defense, grappling, fitness, escapes, sparring, and a less rigid form of one step sparring, which in a way is somewhat like scenario training)) every day of the program. And probably some basic law and first aid concepts.
I assumed you were like a personal trainer and could be with them from sun up to sun down.
Good knowledge of self defense and reasonable sparring skills should be able to prepare most people for scenarios such as ambushes by muggers....unless they are training for bodyguarding and so on.
If they sparred for thirty days with an experienced, trained opponent, their imrpovement would be dramatic. Doing this and hard fitness training, they would leanr self control and get over the adrenaline pump.
It seems like I am trying to pack to much into every day, but think of just like a gym routine - just doing sets of different exercises.
Actually, I question the point of doing it in modules - in a few weeks time, will they remember how to do an evasion to a punch and how to effectively counter it?
