What would be my schedule training for ninjutsu?

If you want to train yourself so you are more prepared for the cles, let me recommend: Improving your short and long distance running, improving your arm strength through pushups, pullups, and working the punching bag, improve your flexibility by stretching alot and practicing your high kicks, and improve your balance through practicing kicks while balancing on the opposite foot for as long as your balance and leg strength allows you(remember to keep your hands up in a defensive position when working on balance). Of course you can also practice the actual MA. of Ninjutsu on your own, but I wouldn't put even half of your training emphasis into that until you have a sensei that can correct you, maybe start that up a week or two before your first cl.
